  • Pseudopodial silica absorption hypothesis (PSA hypothesis): A new function of pseudopodia in living radiolarian polycystine cells
    Kaoru Ogane, Noritoshi Suzuki, Akihiro Tuji, Rie S. Hori, Journal of Micropalaeontology, 33,   2014年01月01日, © 2014 The Micropalaeontological Society.The secretion process of the siliceous skeleton in polycystine radiolarians has drawn a great deal of interest during the last century; however, little is known about the actual physiological process of silica deposition. Recently, the PDMPO (2-(4-pyridyl)-5-[(4-(2-dimethylaminoethylaminocarbamoyl) methoxy)-phenyl] oxazole) method for staining silica deposition sites in polycystines was developed. In the present study we examined over 30 polycystine cells with PDMPO and found that both the skeletons and pseudopodia of three species (Lithelius sp., Rhizosphaera trigonacantha and Arachnosphaera hexasphaera) were stained and emitted green fluorescent light. Staining of the skeleton was probably the result of skeletal thickening growth, whereas staining of the pseudopodia may indicate that siliceous matter is assimilated within pseudopodia. We refer to this hypothesis as the pseudopodial silica absorption hypothesis' (PSA hypothesis). If this hypothesis is correct, PSA is an intermittent process, and the absorbed silica within pseudopodia is quickly transferred to the cytokalymma where it is deposited on the skeleton. To date, the PSA process has been observed in only the three species cited above; therefore we are unable to evaluate whether the PSA process is unique to these species or a common process that occurs in all polycystines; further investigation is necessary.
  • A probable shark dorsal fin spine fragment from the Early Triassic of the Arrow Rocks sequence, Whangaroa, northern New Zealand
    J. A. Grant-Mackie, S. Yamakita, T. Matsumoto, R. S. Hori, A. Takemura, Y. Aita, S. Takahashi, H. J. Campbell, New Zealand Journal of Geology and Geophysics, 57,   2014年01月01日, © 2014 The Royal Society of New Zealand.The ornament on a small external cast in pink chert shows considerable similarity with that of various Middle Palaeozoic and Triassic fish genera. It comes from the Permian-Triassic Oruatemanu Formation of Arrow Rocks, Whangaroa area, eastern Northland. Conodont faunas from a few metres above and below the sample allow correlation with the Neospathodus pakistanensis zone of the Early Triassic, which is assigned to the late Dienerian (late Induan), with adjacent conodont zone faunas in their correct stratigraphic association. The cast is assumed to be that of a small fragment of fin spine, most likely from the junction area of the crown and root on the right-hand side of a dorsal fin spine, possibly anterior, of a marine ctenacanthoid shark, a basal shark order not previously recorded from New Zealand.
  • Evolutionary patterns and palaeobiogeography of Pliensbachian and Toarcian (Early Jurassic) Radiolaria
    Špela Goričan, Elizabeth S. Carter, Jean Guex, Luis O'Dogherty, Patrick De Wever, Paulian Dumitrica, Paulian Dumitrica, Rie S. Hori, Atsushi Matsuoka, Patricia A. Whalen, Palaeogeography, Palaeoclimatology, Palaeoecology, 386,   2013年09月05日, Recent studies on the global distribution of Pliensbachian and Toarcian polycystine radiolarians allowed us to examine faunal turnovers and the biogeography through this critical time interval around a major ecologic and biotic crisis. The analysis is based on the distribution of 167 species belonging to 69 genera. Significant variations in the ratio between the number of originating and extinct species have been recognized. During the early Early Pliensbachian FADs greatly exceeded LADs and the maximum diversity was reached in the late Early Pliensbachian. The trend then reversed with the number of LADs exceeding FADs throughout the Late Pliensbachian and Early Toarcian (extinction interval). Recovery started in the Middle and Late Toarcian, when the number of FADs again surpassed the number of LADs.Three differing evolutionary patterns are observed amongst radiolarian genera through the studied time interval. The largest group diversified rapidly in the Early Pliensbachian and experienced higher extinction rates in the Late Pliensbachian and Early Toarcian; a second group exhibited no major changes; and a third group of mainly spongy spumellarians was successful during the extinction interval. The overall trend of radiolarian diversity is in a fairly good agreement with that of other marine faunas (ammonites and also benthos), but shows an inverse correlation with diversity trends of phytoplankton.Correlation with concomitant environmental changes indicates that radiolarian radiation/extinction rates were not consistently linked with temperature fluctuations or sea-level changes. It is also evident that the diversity decrease started well before the Early Toarcian negative δ13C peak and the Oceanic Anoxic Event (OAE). The extinction interval corresponds well to the duration of a short-term anomaly in the strontium-isotope record, including the rapid decrease of 87Sr/86Sr values in the Late Pliensbachian as well as the rapid increase in the Early Toarcian. This coincidence supports the hypothesis that the predominance of extinctions over originations was caused by a series of climate and environmental changes related to intensified magmatic activity.Some distinct biogeographic differences have been observed. Generic differences are most strongly displayed by the presence or absence of a particular genus or by changes in abundance while species differences range from greater variability to having completely different species in separate palaeolatitudinal realms. Two groups of genera are distinguished: those that are common to abundant in the Tethys (low latitudes) and rare to absent in mid to high latitudes, and those common to abundant in mid to high latitudes and rare to absent in the Tethys. © 2013 Elsevier B.V.
  • Rock magnetic record of the Triassic-Jurassic transition in pelagic bedded chert of the Inuyama section, Japan
    Alexandra Abrajevitch, Alexandra Abrajevitch, Rie S. Hori, Kazuto Kodama, Geology, 41,   2013年07月01日, The end-Triassic mass extinction event is regarded as one of the fi ve largest extinction events of the Phanerozoic. The emerging consensus points to volcanic activity at the Central Atlantic Magmatic Province (CAMP) as the ultimate cause of the extinction, yet the underlying mechanisms and the nature of global environmental changes that accompanied the biotic turnover remain elusive. We present a rock magnetic study of the extinction interval found within a continuous chert sequence that provides an uninterrupted record of pelagic sedimentation in the Panthalassa Ocean. The variations in the relative abundances and characteristics of authigenic magnetic phases indicate that the Triassic-Jurassic transition progressed in two stages. The initial stage, characterized by a disappearance of the previously ubiquitous magnetofossils, started a few tens of thousands of years to 100 k.y. prior to the formal Triassic-Jurassic boundary as identifi ed by the diagnostic radiolarian species. The second stage, defi ned by signifi cant changes in optical and magnetic properties of hematite pigment, lasted a few tens of thousands of years. The stepwise change in magnetic properties is suggestive of the protracted environmental deterioration, likely prompted by the early episodes of the CAMP volcanism, which was followed by a sudden ocean acidifi cation event, perhaps triggered by a catastrophic release of gas hydrates. © 2013 Geological Society of America.
  • Sulfur isotope profiles in the pelagic Panthalassic deep sea during the Permian-Triassic transition
    Satoshi Takahashi, Kunio Kaiho, Rie S. Hori, Paul Gorjan, Takahiro Watanabe, Satoshi Yamakita, Yoshiaki Aita, Atsushi Takemura, K. Bernhard Spörli, Takeshi Kakegawa, Masahiro Oba, Global and Planetary Change, 105,   2013年06月01日, Mesozoic accretionary complexes in Japan and New Zealand contain Panthalassic low latitude and southern mid-latitude deep-water sedimentary rock respectively. These sedimentary rocks record environmental changes in the pelagic Panthalassic Ocean during the transition associated with the severe Permian-Triassic mass extinction. This study presents sulfur isotope records of sulfide from continuous deep-sea Permian-Triassic boundary sections located in northeast Japan (the Akkamori section-2, the most continuous section among other previously reported deep-sea sections) and North Island of New Zealand (the Waiheke-1 section, providing the first sulfur isotopic record from a southern hemisphere deep-sea section). Both sections show sharp ~15‰ drops of the sulfur isotope ratio coupled with a negative shift of organic carbon isotope ratio. Similar decreases in sulfur isotope ratio of carbonate-associated sulfates by ~10‰ accompanied with a negative shift of inorganic carbon isotope ratio at the end-Permian mass extinction horizon have been reported in some shallow water Paleotethyan sections. These sulfur isotope changes suggest that a massive release of 32S-enriched sulfur from the H2S-rich water to the oxic surface-waters coincided with the end-Permian mass extinction. © 2012 Elsevier B.V.
  • An open ocean record of the Toarcian oceanic anoxic event
    D. R. Gröcke, R. S. Hori, J. Trabucho-Alexandre, D. B. Kemp, L. Schwark, Solid Earth, 2,   2011年12月01日, Oceanic anoxic events were time intervals in the Mesozoic characterized by widespread distribution of marine organic matter-rich sediments (black shales) and significant perturbations in the global carbon cycle. These perturbations are globally recorded in sediments as carbon isotope excursions irrespective of lithology and depositional environment. During the early Toarcian, black shales were deposited on the epi- and pericontinental shelves of Pangaea, and these sedimentary rocks are associated with a pronounced (ca. 7 ‰) negative (organic) carbon isotope excursion (CIE) which is thought to be the result of a major perturbation in the global carbon cycle. For this reason, the lower Toarcian is thought to represent an oceanic anoxic event (the T-OAE). If the TOAE was indeed a global event, an isotopic expression of this event should be found beyond the epi- and pericontinental Pangaean localities. To address this issue, the carbon isotope composition of organic matter (σ 13Corg) of lower Toarcian organic matter-rich cherts from Japan, deposited in the open Panthalassa Ocean, was analysed. The results show the presence of a major (6 ‰) negative excursion in σ 13Corg that, based on radiolarian biostratigraphy, is a correlative of the lower Toarcian negative CIE known from Pangaean epiand pericontinental strata. A smaller negative excursion in σ 13Corg (ca. 2‰) is recognized lower in the studied succession. This excursion may, within the current biostratigraphic resolution, represent the excursion recorded in European epicontinental successions close to the Pliensbachian/Toarcian boundary. These results from the open ocean realm suggest, in conjunction with other previously published datasets, that these Early Jurassic carbon cycle perturbations affected the active global reservoirs of the exchangeable carbon cycle (deep marine, shallow marine, atmospheric). © 2011 Author(s).
  • 新潟県蒲原山地の足尾帯泥岩から見出された前期ジュラ紀放散虫化石
    内野 隆之, 堀 利栄, 地質学雑誌, 116, (8) 441 - 446,   2010年, Early Jurassic radiolarian faunae were extracted from mudstone samples collected at three localities (Se1, Ik1, and Jo2) in an accretionary complex within the Ashio Terrane in the Kambara Mountains, Niigata Prefecture, Japan. The faunae of both Se1 and Ik1 are dominated by Canoptum species, in association with two characteristic species belonging to Gorgansium (G. sp. A and G. sp. B) for Se1, and species belonging to Parahsuum, Lantus, and Helvetocapsa for Ik1. The fauna in Jo2 consists mainly of the species of Parvicingula, Zhamoidellum, and gen. et sp. indet. B.
    Based on a comparison of these radiolarians with those from North America, Europe, and Southwest Japan, the ages of the faunae from Se1, Ik1, and Jo2 are Hettangian, Late Pliensbachian, and Middle to Late Toarcian/Aalenian?, respectively.
    This is the first report of radiolarian fossils from terrigenous clastic rocks (mudstone) in the Kambara Mountains; thus, this result contributes to reconstructions of oceanic plate stratigraphy in the region and to correlating the area with other accretionary complexes in the Ashio Terrane.

  • Pseudopodial features and feeding behavior of living nassellarians Eucyrtidium hexagonatum Haeckel, Pterocorys zancleus (Müler) and Dictyocodon prometheus Haeckel
    Kazuhiro Sugiyama, Rie S. Hori, Yoshitaka Kusunoki, Atsushi Matsuoka, Paleontological Research, 12,   2008年09月01日, Light microscopic studies, using both video imaging and normal camera, were made on living nassellarian radiolarians Eucyrtidium hexagonatum Haeckel, Pterocorys zancleus (Müler) and Dictyocodon prometheus Haeckel from the East China Sea off Okinawa Island, Japan. Continuous and careful observations revealed pseudopodial activity related mostly to feeding behavior. The results are presented in detail with the definition of 11 descriptive terms for nassellarian pseudopodia. Among them, terminal projections (TP) extending as straight projections from the aperture of the shell body and forming a conical structure (terminal cone: TC) and axial projections (XP) prolonged outward from the center of the aperture and proximally surrounded by TP are used for feeding. Although there are some minor differences, feeding activities of the three species can be subdivided into the following three cyclic phases; Phase 1 characterized by gradual extension of TP and XP from the aperture, Phase 2 marked by an abrupt withdrawal of TP and XP toward the aperture to engulf captured prey, and Phase 3 during which entangled TP used for capturing prey are completely retracted into the aperture. These lines of evidence suggest that the shell aperture plays the same role of a feeding apparatus as does a mouth. Interestingly, XP of E. hexagonatum sometimes shows abnormal branching, fusion and separation, which is different from the spumellarian axoflagellum. © Palaeontological Society of Japan.
  • The potential of eleocharis acicularis for phytoremediation: Case study at an abandoned mine site
    Nguyen Thi Hoang Ha, Masayuki Sakakibara, Sakae Sano, Rie S. Hori, Koichiro Sera, Clean - Soil, Air, Water, 37,   2009年03月01日, Phytoremediation, a plant-based and cost-effective technology for the cleanup of contaminated soil and water, is receiving increasing attention. In this study, the aquatic macrophyte Eleocharis acicularis was examined for its ability to take up multiple heavy metals and its potential application for phytoremediation at an abandoned mining area in Hokkaido, Japan. Elemental concentrations were measured in samples of E. acicularis, water, and soil collected from areas of mine tailing and drainage. The results reveal that Pb, Fe, Cr, Cu, Ni, and Mn accumulation in the plants increased over the course of the experiment, exceeding their initial concentrations by factors of 930, 430, 60, 25, 10, and 6, respectively. The highest concentrations of Fe, Pb, Zn, Mn, Cr, Cu, and Ni within the plants were 59500, 1120, 964, 388, 265, 235, and 47.4 mg/kg dry wt., respectively, for plants growing in mine drainage after 11 months of the experiment. These results indicate that E. acicularis is a hyperaccumulator of Pb. We also found high Si concentrations in E. acicularis (2.08%). It is likely that heavy metals exist in opal-A within cells of the plant. The bioconcentration factors (BCF: ratio of metal concentration in the plant shoots to that in the soil) obtained for Cr, Cu, Zn, Ni, Mn, and Pb were 3.27, 1.65, 1.29, 1.26, 1.11, and 0.82, respectively. The existence of heavy metals as sulphides is thought to have restricted the metal-uptake efficiency of E. acicularis at the mine site. The results of this study indicate that E. acicularis shows great potential in the phytoremediation of mine tailing and drainage rich in heavy metals. © 2009 WILEY-VCH Verlag GmbH & Co.

  • 四国の三畳系層状チャートから産出したLingularia sp.(腕足類)
    堀 利栄, キャンベル ヘーミッシュ, 地質學雜誌, 110, (12) 758 - 764,   2004年12月15日, 四国東部秩父累帯中の三畳系中部(Lower Anisian)層状チャートよりLingularia sp.(腕足類)の化石が産出した.産出層準は、砥石型珪質粘土岩から頁岩とチャートの等厚互層への漸移部であり、堆積環境が還元状態から回復する過程の貧酸素状態を示す部分である.本標本と類似するLingularia sp.は、ロシア極東シホテアリン山地の下部〜中部三畳系(Spathian-Lower Anisian)層状チャート層の頁岩部やニュージーランド付加体中の層状チャートに伴う中期三畳紀の半遠洋性堆積岩からも見つかっている.この発見は、ペルム紀/三畳紀境界イベントに伴うOAE(海洋貧酸素事変)からの回復過程でいわゆる"Lingula"(本研究でのLingulariaも含む)が大繁栄したという見解を支持し、かつその影響が、古太平洋の深海域まで及んだ可能性を示唆している.

  • 愛媛県砥部町の万年変質安山岩体のボーリングコアにおける硫化鉱物の産状および砥素濃度
    榊原 正幸, 中井 芳恵, 千葉 悦子, 近石 沙知子, 佐野 栄, 堀 利栄, 愛媛大学理学部紀要, 11,   2005年03月25日, Mode of occurrences of sulfide minerals and As concentrations of samples from a HORIzontal boring core of Mannen altered andesite in the Tobe Town, Ehime Prefecture, Japan, has been investigated based on petrography, mineralogy and geochemistry. The Mannen altered andesite intrudes into the vicinity of boundary between the Sanbagawa metamorphic rocks and the Middle Miocene Kuma group. The andesite body has undergone extensive hydrothermal alteration, and has domains of a high concentration of As, S and Sb. Index alteration minerals are pyrite, arsenopyrite, marcasite, stibnite, quartz, opal, carbonate minerals, chlorite, illite and kaolinite. In the Mannen arrear textures of sulphide minerals can be divided into the following six types; sparse, sand spot pool and vein, and black-ink-drawing types. The black-ink-drawing type is characterized by the abundance in marcasite and arsenopyrite. The high concentration domains in arsenic are in general agreement with that characterzed by sulphide minerals of the black-ink-drawing type. Sb, S and As are extremely added and Na_2O, MgO, CaO and FeO are depleted in the Mannen andesites during the hydrothermal alteration on the basis of isocon analyses.
  • 新第三紀熱水活動によって形成された愛媛県西条市・市之川角礫岩における砥素およびアンチモンの挙動
    榊原 正幸, 平岡 良崇, 堀 利栄, 木村 一成, 中島 杏子, 愛媛大学理学部紀要, 11,   2005年03月25日, In this paper, formation process of Ichinokawa breccia and antimony-arsenic mineralization in the breccia in the Ichinokawa area of Saijyo City, Ehime Prefecture, Japan, has been studied on the basis of geological, petrological and geochemical data. We have focussed on "hydraulic fracturing" process for the genesis of the Ichinokawa conglomerate. Ichinokawa conglomerate can be divided mainly into Ichinokawa breccia and Myojin Group. Carbonate-rich breccia and sandstone filling fractures are also found in the Sanbagawa schists adjacent to the Ichinokawa breccia. High-angle breccia zones, the Ichinokawa breccia, cut across the Sanbagawa schistocity. The Ichinokawa breccia consist principally of breccias which have been partly altered and veined by quartz, carbonate minerals and pyrite, and matrix of carbonate-rich sandstone. Schist clasts (up to 10 m across) in the breccia are angular but not variably rotated. Breccias are both clast- and matrix-supported and show evidence for single fracturing and healing by hydrothermally precipitated minerals such as carbonate minerals, pyrite, stibnite, pyrite and quartz. Two Sb and As-rich zones in the Ichinokawa breccia along the Ichinokawa River are about 10-30 m wide adjacent to the Sanbagawa schists. As and Sb values of carbonate matrix in the breccia are extremely high. These observations suggest that the the Ichinokawa breccia formed through a hydrofracturing process associated with hydrothermal fluid infiltrated into Sanbagawa metamorphic as precursor of the antimony ore forming. Hydrothernal fluid seems to have caused mineralization of carbonate minerals and sulfide minerals. Afterwards, the Myojin Group was accumulated above on the Ichinokawa breccia.

    Masayuki Sakakibara, R. S. Hori, Michiharu Ikeda, Misa Umeki, Journal - Geological Society of Japan, 103,   1997年12月01日, Green rock including chert xenoliths has been found in an outcrop of the Pippu area, central Hokkaido, Japan. It is petrologically divided into two types: massive hornblende basalt and picritic basaltic hyaloclastite. The former structurally overlies the latter. The hornblende basalt includes a large amount of chert xenoliths and was subjected to the high-P/T Kamuikotan metamorphism. Radiolarian fossils indicating late Callovian have been obtained from xenoliths of red chert in the hornblende basalt. The picritic basaltic hyaloclastite displays mineral assemblages corresponding to the prehnite-pumpellyite facies. The hornblende basalt is alkalic and rich in TiO2 and P2O5, being similar to oceanic island baslat, whereas picritic basalt is tholeiitic, but very poorer in TiO2 and P2O5 than oceanic ridge basalt. These data suggest that the hornblende basalt belongs to the Kamuikotan complex, whereas the picritic basaltic hyaloclastite is correlative with with Sorachi Group. The Kamuikotan green rocks is inferred to have been generated as intra-plate volcanism after late Calluvian.

  • Origin of cyclicity in Triassic-Jurassic radiolarian bedded cherts of the Mino accretionary complex from Japan
    R. S. Hori, Chang-Fee Cho, H. Umeda, The Island Arc, 3,   1993年12月01日, The abundance of magnetic microspherules in a Triassic-Jurassic continuous sequence of alternating chert and shale beds in the Mino accretionary complex, central Japan, was measured systematically. Depending on time, the magnetic microspherules extracted from shale beds change in abundance considerably from the minimum 0.9 ppm/cm3 at latest Triassic (ca 208 Ma) and the maximum 75 ppm/cm3 at late Early Jurassic (ca 187 Ma); however, the abundance is always higher approximately 10-100 (average 70) times than those from adjacent chert bed at any stratigraphic horizon. Such systematic difference reveals the origin of radiolarian bedded chert as cyclic-rapid accumulation of biogenic SiO2 under extremely slow accumulative environments of shale with probable aeolian dust in origin. Duration time to make a chert-shale couplet corresponds to a dominantly 15-20 Ka interval (average 23 Ka) in Upper Triassic bedded cherts with a low paleolatitude, whereas a 40-45 Ka interval (average 42 Ka) in Lower Jurassic ones which may been formed in higher latitude. The cyclicity of 23 and 42 Ka may correspond to Milankovitch cycles which have been well documented in deep-sea sediments. -from Authors
  • The Toarcian radiolarian event in bedded cherts from southwestern Japan
    Rie S. Hori, Marine Micropaleontology, 30,   1997年03月01日, A drastic faunal turnover of radiolarians in the early Toarcian, termed the Toarcian Radiolarian Event (TRE), recognized in bedded chert sequences of southwestern Japan, is marked by the first co-appearance of the genus Praeparvicingula and Mesosaturnalis hexagonus and by high diversity among multicyrtids. The event resulted in the replacement of latest Triassic through earliest Jurassic taxa by Late Jurassic to Early Cretaceous taxa. At TRE levels in bedded cherts in southwestern Japan, the size of radiolarians decreased drastically, reworked conodont fossils appeared, and anoxic sediments (black cherts with FeS2 nodules) were deposited. The lithologic and faunal changes suggest that global marine environmental changes, including the occurrence of anoxia, caused the TRE.

    R. Hori, T. Otsuka, Journal of Geosciences, Osaka City University, 32, (Art.6) 137 - 161,   1989年12月01日, This paper focuses on the late early Jurassic radiolarian assemblage of bedded cherts and siliceous mudstones in the Mt. Norikuradake area, central Japan. Nine multi-segmented nassellarians of the assemblage including two new species, are described herein. They belong to the genera Hsuum, Parahsuum and Parvicingula and are characterised by forms possessing features of both Parahsuum and Hsuum, with also a form of Parvicingula having small tests. The assemblage containing these taxa, recognisable in various localities in Southwest Japan and North America, is regarded as a fauna of the transitional period from early Jurassic to middle Jurassic forms. This assumption is based on a consideration of the morphology of its component species. On the basis of its biostratigraphic position and faunal content, the assemblage is probably to be dated to a certain time in the late Early to early Middle Jurassic, at least including Toarcian time. -Authors

Three types of taxons were recognized around the T/J boundary, (1) Upper Triassic type such as Squinabolella, (2) Upper Triassic-Lower Jurassic type such as Canoptum, and (3) transition type (possibly earliest Jurassic tye) such as Parahsuum and Bipedis. The radiolarian fossils changed gradually, not drastically, from Triassic type into Jurassic ones during the interval (c7 m.y.) from the extinction of conodonts to the first appearance of a species of Bagotum. -Author
  • Offscraping accretionary process of Jurassic chert-clastic complexes in the Mino-Tamba belt, central Japan
    KIMURA K, HORI R, Journal of Structual Geology, 15, (2) 145 - 161,   1993年01月01日, Detailed structural and biostratigraphical analysis of the Jurassic Inuyama Sequence, a coherent chert-clastic complex in the Mino-Tamba Belt, central Japan, clarifies the evolution of accretionary processes at shallow structural levels. The Inuyama Sequence is characterized by a series of stacked thrust sheets. Each sheet consists of an Early Triassic to Middle Jurassic oceanic plate stratigraphy composed of four lithologic units which are, in ascending order: siliceous claystone; ribbon chert; siliceous mudstone; and clastic rocks. The structural features of the Inuyama Sequence demonstrate a four-stage progressive deformation. (1) A décollement was initiated within the siliceous mudstone when this sequence was just seaward of the deformation front. Clastic dikes and sills formed at the horizon just above the décollement at this time. (2) The stratigraphic section above the décollement was imbricated by in-sequence thrusting in the frontal part of the wedge. This initial stage of thrusting and imbrication was followed by (3) the formation of duplex structures with fault-related folds within the lower stratigraphic section as the décollement stepped down-section to the lowest siliceous claystone interval. Finally, (4) these thrust packages were overprinted by secondary prism thickening in the form of out-of-sequence thrust faulting. © 1993.
  • A model of ocean-crust accretion for the Superior province, Canada
    G. Kimura, J. N. Ludden, J. P. Desrochers, R. Hori, Lithos, 30,   1993年01月01日, One of the keys to understanding the origin of Archaean greenstone belts lies in the geological relationships between mafic and ultramafic greenstones, felsic to intermediate volcanic rocks and terrigenous sediments. Traditional models for greenstone belt evolution have been based on in-situ stratigraphic relationships. Most of these models, for example an oceanic island-arc developed on oceanic basement, back-arc basins, and the recently popular plume model, predict concordant stratigraphic relationships among the various greenstone belt lithologies. However, rather than being depositional in nature, several authors have indicated that many of the relationships between the different lithologies in greenstone belts are in fact tectonic, suggesting an allochthonous origin for most greenstone sequences. All of these latter models make analogies to Phanerozoic tectonic processes involving accretion of oceanic materials with volcanism related to both plate subduction and rifting. In this paper, we have evaluated the geological relationships between volcanic rocks and sediments in three regions in the Superior province, where the accretion of oceanic material can be documented, and direct comparisons are made to geological processes in Phanerozoic accretionary complexes. In the Malartic area in the southeastern Abitibi Subprovince, 3 to 4 km thick slices of komatiite and tholeiite, with intercalated terrigenous sediment, are tectonically imbricated and are overlain by calc-alkaline volcanics which postdate tectonic stacking. In both the Larder Lake region of the southwestern Abitibi belt and in the Beardmore-Geraldton belt, at the south-eastern limit of the Wabigoon belt, slices of iron-rich tholeiite and chemical sediments of an oceanic origin are tectonically imbricated with terrigenous sediment. The Malartic-Val d'Or area is considered to be an example of accretion of an Archaean oceanic plateau, while the Larder Lake and the Beardmore-Geraldton regions are potentially typical of accretion of normal oceanic crust in an arc-environment. Phanerozoic accretion of oceanic crust is accompanied by a step-back in subduction, and in this paper we suggest that oceanic crust accretion may have been the principal mechanism by which the locus of subduction migrated towards the south of the Superior province. Asthenospheric upwelling associated with the isolated sinking plate may have been responsible for widespread late-magmatism. This scenario requires that magmas be erupted through previously accreted volcanic, plutonic and sedimentary material. Furthermore, later ridge subduction will result in transpressional tectonics and eruption of mafic sequences over mature and immature volcano-plutonic sequences. The combined result of the plate tectonic scenario envisaged would result in the well-described "cyclic stratigraphy" of many granite greenstone sequences. © 1993.

  • Triassic radiolarians from the ocean-floor sequence of the Waipapa Terrane at Arrow Rocks, Northland, New Zealand
    Atsushi Takemura, Yoshiaki Aita, Rie S. Hori, Yasushi Higuchi, K. Bernhard Spörli, Hamish J. Campbell, Kazuto Kodama, Toyosaburo Sakai, New Zealand Journal of Geology and Geophysics, 45, (45) 289 - 296,   2002年09月01日, Triassic radiolarians are reported from two horizons in Waipapa Terrane at Arrow Rocks, Whangaroa area, Northland. This relatively undisturbed succession represents an ocean-floor sequence, consisting (in ascending order) of basalt with limestone layers, bedded chert, black shale, and red, maroon and green siliceous mudstone. The age of the lower part of the section is Middle-Late Permian. The radiolarian assemblages reported here indicate Early or Middle Triassic and Middle Triassic (Anisian) ages for maroon siliceous mudstones in the upper part of the section. Between strata of known Permian and Triassic age there is a thin potential Permian/Triassic boundary interval consisting of alternating black shale and grey chert. Radiolarian paleogeography indicates that the Arrow Rocks sequence experienced long distance plate tectonic displacement from a position of relatively low latitude in the Middle Permian and to a high latitude in mid-Triassic time.

  • Preliminary report on Lower Jurassic Radiolaria of Gondwana origin from the Kawhia coast, New Zealand
    HORI R S, AITA Y, GRANT‐MACKIE J A, The Island Arc, 5, (2) 104 - 113,   1996年01月01日, Well-preserved radiolarians from the Newcastle Group in southwest Kawhia, New Zealand, constitute the first record of Lower Jurassic radiolarians from in situ deposits in high latitudes of the Southern Hemisphere on the margin of Gondwana. The radiolarians were extracted from carbonate nodules from five horizons in the Rewarewa Formation and the lower part of the Arawhero Formation, in the Murihiku Terrane. The radiolarian-bearing sequence, which lies within the upper part of the type section of the local Aratauran Stage, is roughly datable as Hettangian-Sinemurian from rare ammonite occurrences. The radiolarian assemblages consist, on average, of 80-90% spumellarians and 10-20% nassellarians. Spumellarians include species of the following genera: Archaeotriastrum, Cnicella, Emiluvia (?) Homeoparonaella, Orbiculiforma, Pantanellium, Paronaella (?), Pseudocrucella, Pseudoheliodiscus, Spongostaurus and Spongotrochus. Nassellarians are composed of species of Bagotum, Bipedis, Droltus, Jacus (?) Perispyridium (?) Raoultius, Riedelius, Saitoum and Thetis. From data of Lower Jurassic radiolarian faunas of Europe, North America and Japan, the New Zealand fauna shows stronger affinity with those of the European Tethys such as Turkey (e.g. De Wever 1982) and the Northern Alps (Kozur & Mostler 1990) than with faunas from other areas of the circum-Pacific. This connection between the European Tethyan and New Zealand faunas is not well explained by presently accepted continental reconstructions (Smith et al. 1994) for the Early Jurassic.

    千葉 悦子, 榊原 正幸, 佐野 栄, 堀 利栄, 中井 芳恵, 愛媛大学理学部紀要, 11,   2005年03月25日, The weathering process of Mannen altered andesite in Tobe Town, Ehime Prefecture, Japan, has been investigated based on geology, petrography and geochemistry. The Mannen andesite intrudes into the Sanbagawa metamorphic rocks and the Middle Miocene Kuma group. The andesite dyke have undergone extensive hydrothermal alteration and mineralization, and has domains of a high concentration of As, S and Sb. Index alteration minerals are pyrite, arsenopyrite, marcasite, stibnite, quartz, carbonate, chlorite, titanite and illite. The weathering types in the near surface of the Mannen andesite is divided into five based on the degree of progress of weathering. That results show that domains of sulphide minerals-rich altered andesite are extremely weathered. CaO, Fe_2O_3, MgO, Pb, Cu, Sb, S and As are depleted in weathered parts of the Mannen andesite based on isocon analysis. Especially, Fe_2O_3, S and As are extremely depleted in weathered parts of sulphide minerals-rich altered andesites. It shows that sulphide minerals in the andesite are decomposed by interaction of surface water and microbial activity, and these elements are leaching away to surrounding environments.

  • A new Early Jurassic radiolarian fauna from the Murihiku Supergroup of the Otago coast, New Zealand
    R. S. Hori, J. D. Campbell, J. A. Grant-Mackie, New Zealand Journal of Geology and Geophsics, 40,   1997年09月01日, Lower Jurassic Radiolaria are documented from Aratauran strata of the Murihiku Supergroup at the northern end of Sandy Bay, south of Nugget Point, Otago, New Zealand. The fossils were extracted from small carbonate nodules in fine grey sandstone in the middle part of the Aratauran sequence. The following genera were identified: Eptingium(?), Gigi, Hsuum, Orbiculiforma, Pantanellium, Paronaella(?), Poulpus(?), Saitoum, Spongostaurus(?), and Thetis. Comparison with radiolarian faunas of Europe, southwest Japan, and North America suggests that the study fauna is of Pliensbachian age, probably Early Pliensbachian, indicating the possibility that the Aratauran local stage, previously equated approximately with Hettangian-Sinemurian internationally, extends into the Early Pliensbachian.

  • Sorption of antimony in stream water by weathered and altered rock
    Sakae Sano, Masayuki Sakakibara, Etsuko Chiba, Rie Hori, Contaminated Soils, 12,   2007年12月01日, The ionic migration of antimony in various weathered and country rocks during chemical weathering was studied The Ichinokawa abandoned mine of Shikoku Island, Japan is famous for the production of stibnite. The antimony deposits are mainly in Sambagawa metamorphic rocks and the brecciated rocks (Ichinokawa breccia) formed through a hydro-fracturing process associated with hydrothermal fluid related to Tertiary igneous activity around the area. Antimony content in stream water around the mine was extremely high (over 200 □g/L), which indicates that antimony dissolves into the water from the country rocks by chemical weathering. We examined the antimony contents in variously weathered and altered country rocks in the streambed, to understand the transfer of the element into the stream water. Consequently, antimony content in brown-colored, strongly weathered and altered part of the rocks was higher than that in the unweathered (or weakly weathered) part. The antimony content in the strongly weathered part was several tens to hundreds ppm, although the content in unweathered part was significantly low, sometimes under the detection of XRF. This may indicate that the antimony in the stream water is adsorbed selectively in the strongly weathered and altered part of the streambed rock. The strongly weathered and altered rocks contain many iron hydroxides, which may trap antimony ion from the water. A similar phenomenon was observed in the other area. This suggests that a high distribution of antimony ion into the strongly weathered and altered rocks including iron hydroxides against the water is ubiquitous.
  • Platinum group element anomalies and bioevents in the Triassic-Jurassic deep-sea sediments of Panthalassa
    Rie S. Hori, Toru Fujiki, Eriko Inoue, Jun Ichi Kimura, ElsevierPalaeogeography, Palaeoclimatology, Palaeoecology, 244, (1-4) 391 - 406,   2007年02月09日, Micropalaeontological and geochemical analyses were performed on samples from a continuous sequence of bedded chert from the Kurusu (KU) section, Inuyama area, southwest Japan. The sequence contains the Triassic-Jurassic (T-J) boundary and is representative of deep-sea sediments from Panthalassa. The succession records a rapid, stepwise extinction pattern of radiolarian faunas, and the disappearance of conodonts at the T-J boundary. Comparison of micropalaeontological results and geochemical data reveals anomalously high abundances of platinum group elements (PGEs) in the latest Rhaetian, at the beginning of the radiolarian extinction at the T-J boundary. The PGE anomaly suggests that the radiolarian ooze of Panthalassa was contaminated by siderophile-rich materials during the late Rhaetian. The rare earth element (REE) pattern shows no distinct change across the T-J boundary, except for one significant positive Ce anomaly immediately below the PGE anomaly. These geochemical signatures imply the anomalous input of PGE-rich materials, but no obvious anoxic event in deep-sea sediments during latest Triassic time. The PGE anomaly at the end of the Triassic may be linked to the first phase of marine plankton extinction, but would not have been directly connected with the main radiolarian extinction at the T-J boundary. © 2006 Elsevier B.V.

  • Triassic Radiolaria from Kaka Point Structural belt, Otago, New Zealand
    R. S. Hori, J. D. Campbell, J. A. Grant-Mackie, The Royal Society of New ZealandJournal of the Royal Society of New Zealand, 33, (1-4) 39 - 55,   2003年03月01日, Triassic Radiolaria are documented from phosphatic nodules obtained from the Karoro Formation and Potiki Siltstone from Kaka Point Structural Belt, Otago, New Zealand. There are abundant Glomeropyle and Spumellaria, and rare Nassellaria and Entactinaria. By comparison with radiolarian faunas from Japan, Thailand, European Tethys, and other Triassic strata in New Zealand, the Karoro Formation is correlated with upper Lower Triassic (Olenekian), older than the Potiki Siltstone. We believe that the fauna is strongly affected by non-Tethyan radiolarians based on the abundance of Glomeropyle, rare occurrence of Tethyan taxa, and the presence of many undescribed forms. Three new species are described herein: Glomeropyle bispinosa, G. campbelli, and Poulpus (?) caveaformis.

  • Global correlation of the radiolarian faunal change across the Triassic-Jurassic boundary
    CARTER Elizabeth S., HORI Rie S., NRC CanadaCanadian Journal of Earth Sciences, 42, (5) 777 - 790,   2005年05月01日, Precise comparison of the change in radiolarian faunas 3.5 m above a U-Pb zircon dated 199.6 ± 0.3 Ma tuff and approximately coincident with a negative δ13C anomaly in the Queen Charlotte Islands, B.C. (Canada) with Inuyama (Japan) sequences indicates that major global changes occurred across the Triassic-Jurassic (T-J) boundary. Nearly 20 genera and over 130 Rhaetian species disappeared at the end of the Triassic. The index genera Betraccium and Risella disappear and the final appearance of Globolaxtorum tozeri, Livarella valida, and Pseudohagiastrum giganteum sp. nov. are also diagnostic for the end of the Triassic. The low-diversity Hettangian survival fauna immediately above the boundary is composed mainly of small, primitive spumellarians with spongy or irregularly latticed meshwork and rod-like spines, and new genera Charlottea, Udalia, and Parahsuum s.l. first appear in the lowest Hettangian in both localities. Irrespective of different sedimentation rates and sedimentary environments, such as shelf to upper slope (Queen Charlotte Islands) and deep sea below carbonate compensation depth (CCD; Inuyama), radiolarians show a similar turnover pattern at the T-J boundary. © 2005 NRC Canada.

Pot-scale experiment evaluated phytoremediation by Pteris vittata L. (Chinese brake fern) for mudstone containing arsenic (12.3 mg/kg-DW) of the Hakobuchi Group in the Yubari City, central Hokkaido, Japan. In this experiment, fronds of Pteris vittata L. were taken after 18 weeks growth in soil. The following properties became clear after examining the experimental results. (1) The brake fern can growth in the soil made from mudstone containing arsenic. (2) The highest arsenic concentrations in the frond of Pteris vittata L. growing in the soil are about 3000 mg/kg-DW. (3) The fern removed arsenic about 10 % from mudstone. The results suggested that the brake fern has a great poten tial to be used for phytoremediating soils with low concentration of arsenic.
  • Evidence from radiolarian chert xenoliths for post-Early Jurassic volcanism of the Mikabu greenrocks, Okuki area, western Shikoku, Japan
    M. Sakakibara, R. S. Hori, T. Murakami, Journal of the Geological Society of Japan, 99, (10) 831 - 833,   1993年12月01日, The Mikabu greenrocks extend more than 800 km in length in the outer zone of Southwest Japan. They are composed mainly of volcanic sedimentary rocks, basalts, dolerite, gabbro, and ultrabasic rocks, and are associated with minor limestone and chert. Recently, the Mikabu greenrocks have been interpreted to be accreted oceanic plateaus or seamounts. Red radiolarian chert xenoliths have been found in the Mikabu dolerite, Okuki area, western Shikoku. The paper discusses the geological significance of the fossil evidence constraining the formative age of the Mikabu greenrocks. -from Authors

  • Late Triassic phaeodarian Radiolarian from the Northern Chichibu Belt, Shikoku, Japan
    HORI Rie S., YAMAKITA Satoshi, DUMITRICA Paulian, 日本古生物学会, 13, (1) 53 - 63,   2009年04月01日, A new genus (Triassiphaeodina gen. nov.) and two new species (Medusetta japonica sp. nov. and Triassiphaeodina niyodoensis sp. nov.) of Late Triassic (Rhaetian) phaeodarian Radiolaria are described from a phosphatic nodule found in mlange rocks of the Northern Chichibu Belt, Shikoku, Japan. The Rhaetian age of the nodule and of the phaeodarian new taxa is based on co-occurring Polycystina Radiolaria, including Bipedis acrostylus Bragin, Livarella densiporata Kozur and Mostler, Fontinella primitiva Carter, and Ferresium sp. A of Carter (1993). This finding shows that phaeodarian Radiolaria were already represented in Late Triassic oceans, with morphologies similar to those known in the Late Cretaceous and Cenozoic, from which they have previously been reported. The new taxa described herein represent the oldest known phaeodarian fossils. © by the Palaeontological Society of Japan.
  • Lower Jurassic (Hettangian-Sinemurian) radiolarian assemblages from black cherts in the Wakai accretionary complex, Ikuno area, Tamba Terrane, Southwest Japan
    Susumu Shibutani, Rie S. Hori, Micropaleontology Project, Inc, New YorkStratigraphy, 5, (1) 83 - 98,   2008年07月14日, Well-preserved Lower Jurassic (Hettangian-Sinemurian) radiolarian fossils were obtained from black chert and shale of the Wakai complex in the Ikuno, area, Tamba Terrane, Southwest Japan. These faunas are dominated by the genera Natoba, Canoptum, Ovumella, and Droltus. We define a Natoba-rich Assemblage as one containing >10% Natoba in the nassellarian assemblage. This assemblage is also characterized by relatively high abundance of Canoptum and Ovumella (combined abundance >15% nassellarian assemblage) and a low nassellarian/spumellarian ratio (<0.2). Based on data from Lower Jurassic radiolarian faunas from Japan, the Natoba-rich Assemblage is very similar to the Canoptum Assemblage. These two assemblages both contain common Natoba and occur exclusively in fine-grained silicielastic rocks and black cherts. Considering the global distribution of Natoba, the Natoba-rich Assemblage appears to be restricted to oceanic regions peripheral to the western Panthalassa and Tethys.

  • Early Triassic (Induan) Radiolaria and Carbon-isotope ratios of a deep-sea sequence from Waiheke Island, North Island, New Zealand
    Rie S. Hori, Satoshi Yamakita, Minoru Ikehara, Kazuto Kodama, Yoshiaki Aita, Toyosaburo Sakai, Atsushi Takemura, Yoshihito Kamata, Noritoshi Suzuki, Satoshi Takahashi, K. Bernhard Spörli, Jack A. Grant-Mackie, ElsevierPalaeoworld, in press,   2011年08月01日, This study examines a Triassic deep-sea sequence consisting of rhythmically bedded radiolarian cherts and shales and its ifcmplications for early Induan radiolarian fossils. The sequence, obtained from the Waipapa terrane, Waiheke Island, New Zealand, is composed of six lithologic Units (A-F) and, based on conodont biostratigraphy, spans at least the interval from the lowest Induan to the Anisian. Unit A (the basal unit) consists of black chert and shale beds containing fine pyrite minerals; this corresponds to the oceanic anoxic event described at Arrow Rocks further north in New Zealand. The δ13Corg values of Unit A show a pronounced negative shift between the pale-green chert and black shale/chert, which may represent the negative excursion across the Permian-Triassic boundary that has been documented worldwide. The black cherts, which give minimum C-isotopic ratios (around -30‰), are early Induan, and contain a rich radiolarian fauna characterized by Entactinosphaera? crassispinosa Sashida and Tonishi, E.? spoerlii Takemura and Aono, Bistarkum martiali Feng, Entactinia cf. itsukaichiensis Sashida and Tonishi, Ellipsocopicyntra? sp., and rare Nassellaria. A new Induan nassellarian species, Tripedocorbis? blackae n. sp., from the black chert bed, is described herein. Its presence indicates that Triassic-type Nassellaria had already appeared in the early Induan in the pelagic realms of southern hemisphere Panthalassa. © 2011 Elsevier Ltd and Nanjing Institute of Geology and Palaeontology, CAS.
  • Stratigraphy of Triassic-Jurassic boundary sequences from the Kawhia coast and Awakino gorge, Murihiku Terrane, New Zealand
    Kenichi Akikuni, Vivi Vajda, Rie S. Hori, Jack A. Grant-Mackie, Minoru Ikehara, Micropaleontology PressStratigraphy, 7,   2010年11月24日, We have examined the stable carbon isotope stratigraphy, bio- and litho-stratigraphy of the Upper Triassic (Otapirian) - Lower Jurassic (Aratauran) boundary strata from the Awakino gorge and Kawhia coast sections, Murihiku Terrane, North Island, New Zealand. Successive occurrences of species of the bivalve genus Otapiria, O. dissimilis, O. marshalli and O. aff. marshalli, and also of age diagnostic ammonites indicate that the Hettangian strata in both sections are very thin compared with the Rhaetian sequences. Lamination structures are well developed at the Tr-Jr (Rhaetian- Hettangian) boundary transition interval. The δ: 13 values of organic matter from siltstone and carbonate nodules in the sedimentary rocks range from -28.5 to -25.5%o and there is no correlation between δ: 13C and C/N ratios. The excursion patterns of δ: 13Corg from both sections are similar, showing a negative spike at the uppermost Rhaetian and a positive spike immediately below the Tr-Jr boundary. A long-lived positive shift is also recognized in the Awakino gorge section, which coincides in pattern with those reported in Tr-Jr boundary successions from the Queen Charlotte Islands, British Columbia, Canada. These results suggest that although magnitude and absolute values are slightly different, the integrated pattern of stable carbon isotope signatures over the Tr-Jr boundary could be a valuable tool for correlation, at least between sedimentary rocks from similar depositional settings in the Panthalassa.

  • Direct observation of the skeletal growth patterns of polycystine radiolarians using a fluorescent marker
    OGANE K., TUJI A., SUZUKI N., MATSUOKA A., KURIHARA T., HORI R.S., ElsevierMarine Micropaleontology, 77, (3-4) 137 - 144,   2010年12月01日, Skeletogenesis in polycystine radiolarians was detected, using a fluorescent compound called PDMPO (2-(4-pyridyl)-5-[(4-(2-dimethylaminoethylaminocarbamoyl)methoxy)-phenyl] oxazole). This compound binds under acidic conditions with silica in the silica deposition vesicle (SDV) of radiolarians, and only newly added silica emits a green fluorescence under ultraviolet light. We used cells fixed with formaldehyde of two species of spherical Spumellaria (Hexacontium philosophica and Rhizosphaera trigonacantha) and three species of cyrtid Nassellaria (Anthocyrtidium angulare, Clathrocyclas (?) cassiopeiae, and Lophophaena hispida), in which green fluorescence occurred in the entire skeleton outside the endoplasm. In contrast, the conical nassellarian species Eucyrtidium hexagonatum emitted green fluorescence only on the cephalo-thorax-abdominal part of the skeleton, and on part of the inner ring at the segmental suture, and the margins of pores, suggesting partial biological silicification. Two flat spumellarian species (Dictyocoryne profunda and Rhopalastrum elegans) showed bright green fluorescence over the full skeleton in some cells, but other cells did not fluoresce at all, even though young cells in good condition were tested, suggesting that intermittent growth occurs in these species, as known from a controlled incubation experiment. We did not observe development of new skeletons, but "skeletal thickening growth" (STG), defined as silica deposition over the surface of an existing skeleton, occurred to varying degrees in the polycystines, and may result in the formation of lamellar structures, as observed in sectioned skeletons of polycystines. © 2010 Elsevier B.V.
  • Lead isotopic record of Barremian-Aptian marine sediments: implications for large igneous provinces and the Aptian climatic crisis
    Junichiro Kuroda, Junichiro Kuroda, Masaharu Tanimizu, Rie S. Hori, Katsuhiko Suzuki, Katsuhiko Suzuki, Nanako O. Ogawa, Maria L G Tejada, Maria L G Tejada, Millard F. Coffin, Rodolfo Coccioni, Elisabetta Erba, Naohiko Ohkouchi, ElsevierEarth and Planetary Science Letters, in press,   2011年07月01日, We present initial isotopic ratios of lead for Early Cretaceous (Barremian-Aptian) sections from Shatsky Rise (Pacific) and Gorgo a Cerbara (Italy). Our Pb isotopic data track an interval representing Oceanic Anoxic Event (OAE)-1a, which is characterized by quasi-global deposition of organic carbon-rich black shale. Pb isotopic compositions of sediments from Shatsky Rise decrease at the end of Barremian time, from radiogenic continental values to unradiogenic values, and subsequently remained less radiogenic until the end of early Aptian time. We explain the isotopic shift by a significant increase in supply rate of unradiogenic Pb, most likely due to massive volcanism. In contrast, the Pb isotopic compositions from the Italian section, which was situated at the western end of Tethys, are mostly identical to those of upper continental crust, showing no significant change in supply rate of unradiogenic Pb. The discrepancy between two sites is attributed to quiescent deep-submarine eruptions of Pacific large igneous provinces (LIPs) such as the Ontong Java Plateau (OJP), which severely limited dispersion of Pb-carrying particles out of the Pacific Ocean. Published Os isotopic data from the Italian section indicate two episodes of massive eruptions of OJP or contemporaneous Manihiki and Hikurangi plateaus starting from earliest Aptian time, slightly later than that indicated by the sedimentary Pb isotopic record from Shatsky Rise. Differences in isotopic variations between Pb and Os likely reflect differences in their chemical behaviors in the oceans, i.e., Pb isotopic compositions would have varied in response to local or regional changes in sediment provenances, whereas large-scale changes in Os inputs are required to explain variations in seawater Os isotopic compositions. Our Pb isotopic data, together with the published Os isotopic record, provide new evidence for the eruptive history of OJP together with contemporaneous Pacific plateaus and its environmental consequences, starting from end-Barremian time and extending through early Aptian time. © 2011 Elsevier B.V.
  • A marine osmium isotope record across the Triassic-Jurassic boundary from a Pacific pelagic site
    KURODA Junichiro, KURODA Junichiro, HORI Rie S., SUZUKI Katsuhiko, GROECKE Darren R., OHKOUCHI Naohiko, Geological Society of AmericaGeology, 38, (12) 1095 - 1098,   2010年12月01日, The Triassic-Jurassic (T-J) boundary ca. 200 Ma represents one of the major mass extinction events of the Phanerozoic; however, the cause of this event remains controversial because of a paucity of geological evidence. In this study we present an isotopic record of osmium extracted from a bedded chert succession across the T-J boundary in the Kurusu section of Japan, deposited within a Paleo-Pacific (Panthalassa) deep basin. The data show a gradual decrease in seawater 187Os/188Os values during the Rhaetian, followed by a sharp increase in the latest Rhaetian, and a subsequent stable phase across the T-J boundary. The decreasing trend of 187Os/188Os values during the Rhaetian indicates a gradual increase in the relative supply rate of unradiogenic Os from the mantle associated with emplacement of the Central Atlantic Magmatic Province. The subsequent shift toward radiogenic values reflects an increased supply of radiogenic Os due to enhanced continental weathering. This interval marks more negative isotopic values of organic carbon, the onset of radiolarian faunal turnover, and conodont extinctions, indicating that the rapid increase in continental weathering rate was closely linked to the perturbation of the carbon cycle and the T-J biotic crisis. © 2010 Geological Society of America.

  • Global radiolarian zonation for the Pliensbachian, Toarcian and Aalenian
    Elizabeth S. Carter, Špela ̌ Goričan, Jean Guex, Luis O'Dogherty, Patrick De Wever, Paulian Dumitrica, Rie S. Hori, Atsushi Matsuoka, Patricia A. Whalen, ElsevierPalaeogeography, Palaeoclimatology, Palaeoecology, 印刷中,   2010年11月10日, Jurassic radiolarians from 220 samples in Queen Charlotte Islands, B.C., Williston Lake, B.C., east-central Oregon, Baja California Sur, southern Spain, Austria, Slovenia, Turkey, Oman, Japan and Argentina were studied in order to construct global zonation for the Pliensbachian, Toarcian and Aalenian stages. Well-preserved faunas from continuous stratigraphic sections in Queen Charlotte Islands provide the most detailed record for this time interval, and all collections are tied to North American ammonite zones or assemblages. Collections from nearly all other areas lack independent dating except for early Toarcian carbon-isotope dating in Slovenia and late Aalenian ammonites in Spain.A database of 197 widely distributed updated taxonomic species was used to construct a Unitary Association (UA) zonation for the interval. A global sequence of 41 UAs was obtained for the top of the Sinemurian to the base of the Bajocian. The first and the last UAs represent the Late Sinemurian and the Early Bajocian respectively. The remaining 39 UAs were merged into nine zones (four Early Pliensbachian, one Late Pliensbachian, one Early Toarcian, one Middle-Late Toarcian, and two Aalenian) according to prominent radiolarian faunal breaks and ammonite data. The new zones are the Canutus tipperi - Katroma clara Zone (latest Sinemurian/earliest Pliensbachian); Zartus mostleri - Pseudoristola megaglobosa, Hsuum mulleri - Trillus elkhornensis and Gigi fustis - Lantus sixi zones (Early Pliensbachian); Eucyrtidiellum nagaiae - Praeparvicingula tlellensis Zone (Late Pliensbachian); Napora relica - Eucyrtidiellum disparile Zone (Early Toarcian); Elodium pessagnoi - Hexasaturnalis hexagonus Zone (Middle and Late Toarcian); Higumastra transversa - Napora nipponica Zone (early Aalenian); and Mirifusus proavus - Transhsuum hisuikyoense Zone (late Aalenian). These zones can be correlated worldwide and link previously established UA zonations for the Hettangian-Sinemurian and the Middle to Upper Jurassic. The new zonation allows high-resolution dating in the studied interval and provides a solid basis for analyzing faunal turnovers and the paleobiogeography of Jurassic radiolarians. © 2010 Elsevier B.V.
  • Magnetization carriers and remagnetization of bedded chert
    ABRAJEVITCH Alexandra, HORI Rie S., KODAMA Kazuto, ElsevierEarth and Planetary Science Letters, 305, (1-2) 135 - 142,   2011年05月01日, Bedded chert is the only sediment type representative of the Paleozoic to early Mesozoic pelagic marine environment. Because of their association with ophiolites and island arc rocks, presence of datable microfossils and paleohorizontal reference provided by well-developed bedding surfaces, bedded chert sequences are often targeted for paleomagnetic tectonic studies. However, processes of magnetization acquisition in biosiliceous sediments, and consequently, the significance of their magnetic record, are not well understood. Our rock magnetic study of a Triassic-Jurassic radiolarian chert sequence, the Mino Terrane, Central Japan, shows that the ferrimagnetic assemblage of the gray chert units is of detrital origin, while the red chert's assemblage is dominated by authigenic phases - pigmentary hematite and biogenic magnetite - which contribute to the natural remanent magnetization. The presence of magnetofossils places red oxic chert in the category of prospective environmental archives. Magnetite-producing magnetotactic bacteria were apparently able to tolerate elevated concentrations of dissolved silica as well as a steep redox gradient in sedimentary pore-waters during the deposition of red chert layers. A strong uniaxial anisotropy due to chain-alignment of the biogenic magnetite grains likely contributes to the acquisition of anomalously stable partial thermoviscous magnetization by chert even at low metamorphic temperatures. © 2011 Elsevier B.V.
