地球史を通した生命進化は、地球環境異変とそれに続く大量絶滅により駆動されてきました。しかし、環境変動を引き起こした主要因や、絶滅から多様化へ至る過程は各時代で異なるシナリオが提案されています。研究室では、生物大量絶滅が記録されている時代境界の連続堆積物試料を対象として、小惑星衝突や火山活動に鋭敏な地球化学的トレーサーとなる元素濃度・同位体比変動を高分解能で解析することにより、巨大天体衝突や大規模噴火にともなう大気–海洋系の変動メカニズムや生態系の応答を明らかにすることを目指しています。

    The Carnian Pluvial Episode (CPE) was a short interval of extreme rainfall in the Late Triassic that caused significant changes in marine ecosystems. Global warming induced by Wrangellia volcanism is thought to have resulted in oceanic anoxia during the CPE, but the global extent, duration, and severity of anoxia, and its effects on major marine taxa, remain unclear. To address this, we examined an equatorial record of conditions in the Panthalassa Ocean during the CPE, focusing on marine Os isotope data, redox conditions, and conodont and radiolarian biostratigraphy. The results show that Wrangellia volcanism peaked in the latest Julian (early Carnian), coinciding with development of reducing conditions in the deep-sea Panthalassa. A strong conodont turnover occurred during the period of oceanic anoxia, whereas radiolarians were less affected and their diversity increased after the recovery from anoxia. The increased radiolarian diversity during the early Tuvalian (late Carnian) can be attributed to chemical weathering and enhanced nutrient fluxes associated with global warming and the more humid climate of Pangea.

    We investigated the geochemical and rock magnetic properties of the magnetostratigraphically calibrated Pignola-Abriola section (Italy) in order to understand the climatic perturbations that characterize the late Norian-early Rhaetian interval (Late Triassic). We performed experiments on anhysteretic and isothermal remanence (ARM and IRM) and on magnetic susceptibility (χ) to obtain the rock magnetic parameters necessary for our paleoclimatic investigation. An episode of increase in the relative quantity of hematite, suggesting the enhanced subaerial oxidation of iron minerals, was identified in the Norian from ~217 Ma in the Alaunian up to ~211 Ma in the early Sevatian, followed by a decline up to 207-206 Ma at the end of the Norian (late Sevatian). The results of geochemical and multivariate statistical analyses support a long-term increase and reduction in rock weathering, confirming and extending previous 87Sr / 86Sr data from the Pizzo Mondello section (Italy). Possible causes of these long-term weathering trends are the multiphase uplifting of the Cimmerian orogen, occurring at mid-northern latitudes along the southern margin of Asia in the Late Triassic, and/or the northward motion of Pangea across the equatorial humid belt. Rapid excursions in oxidized iron minerals have also been observed across the Norian-Rhaetian boundary, the origin of which still has to be determined.

    The late Norian “chaotic carbon episode” in the Late Triassic has been identified in North America, Italy, and China, reflecting a global carbon isotope perturbation. Although it has been suggested that catastrophic events, such as the emplacement of large igneous provinces, were the cause of this perturbation, direct evidence for volcanic forcing is lacking. In order to investigate the cause of the global “chaotic carbon episode” in the late Norian, we obtained osmium and organic carbon isotope data (187Os/188Os and δ13Corg) and major, trace, and highly siderophile element data and documented changes in radiolarian assemblages in a middle–upper Norian bedded chert succession in the Sakahogi section, Japan, deposited in a low-latitude zone of the Panthalassa Ocean. The δ13Corg data exhibit a significant carbon isotope excursion (CIE) during the late Norian (Sevatian 1) Mockina bidentata conodont zone. High-resolution 187Os/188Os data exhibit two negative shifts during the CIE, which are interpreted as related to volcanic activity. The biostratigraphic age and Os isotopic mass balance considerations for the ocean suggest that the onset of Angayucham volcanism was the source of unradiogenic Os that caused the decrease in seawater 187Os/188Os ratios during the Sevatian. A remarkable diversification of radiolarians with a large Mesosaturnalis bloom occurred during the low-187Os/188Os interval. This suggests that the Sevatian Mesosaturnalis species are likely indicators of the onset of Angayucham volcanism.

    The end-Triassic extinction event (∼ 201.5 Ma) is one of the five major mass extinction events in Earth's history, however, considerable discussion continues on the exact causes and timing of the event. This is because, whilst certain geochemical data on T-J sections appears to be largely comparable globally, with for example a significant (up to 6‰) negative carbon-isotope (δ13C) excursion at the extinction horizon, more often than not other geochemical variations are neither uniform nor fully consistent between sections. Critical to this discussion is that the majority of the studied sections containing the end-Triassic extinction event are limited to shallow marine or terrestrial sections, which are prone to discontinuities and hiatuses. In this study, we present carbon isotopes (δ13Ccarb), total organic carbon (TOC), major and trace, mercury (Hg) and highly siderophile elements (HSE), osmium-isotope compositions and paleomagnetic data of a relatively less studied deep-marine T-J succession in the Budva Basin, Čanj, Montenegro. At Čanj, deep-marine Triassic limestones are abruptly interrupted by a ∼ 6 cm finely laminated clay layer, before transitioning to more argillaceous Jurassic red beds. The clay layer is interpreted to represent the end-Triassic extinction interval and is characterized by a negative carbon isotope excursion, relative heavy rare earth element (HREE) enrichment, Hg increase, HSE enrichment and a sharp shift to unradiogenic osmium-isotopic ratios. This establishes the Čanj section as a unique and well-preserved outcrop that exquisitely encapsulates the end-Triassic extinction in the Tethyan marine realm. The distinct geochemical markers recorded at Čanj are consistent with the Central Atlantic Magmatic Province as the main driver behind the end-Triassic extinction.

    Application of the rhenium (Re) and osmium (Os) isotope system is a useful way to date geological materials, trace their circulation, and reconstruct the Earth's surface environment. However, measurements on less than 15 pg of Os have been challenging because of the large contribution of Os from external sources and insufficient ion beam intensity of instruments. Here, we present a measurement procedure we developed for Re and Os isotope analyses that minimizes contamination of Os from external sources and enables measurements on less than 15 pg of Os with high accuracy and precision by using a multiple collector-inductively coupled plasma-mass spectrometer equipped with compact discrete dynode (CDD) ion-counting detectors. The cleaning procedure we developed for laboratory equipment reduced the amount of Os from external sources to 0.002-0.015 pg, one order of magnitude lower than previously reported values. The measurements of Os isotope standard samples containing less than 30 pg of Os by the use of CDD detectors with in-run cross-calibration of differences in counting efficiencies of CDD detectors produced data with much better precision than those produced by using Faraday cup detectors. The measurement results of geological reference materials, JMS-2 and JCh-1, demonstrated that our method using CDD detectors yielded geochemical data with in-run precision that were equivalent to or better than those obtained by conventional procedures. The method enabled reduction of the sample volume and thus enabled high-spatial-resolution analysis with a small amount of the geological sample.

    巨大天体衝突によって供給された宇宙物質の化学的痕跡は，地球由来物質との混合によって希釈され，衝突天体の起源を厳密に決定することは極めて難しい．そのため本研究では，ミリグラムレベルでの微小試料から衝突物質の混入率とその起源を同時に求める新たな地球化学的分析法を確立する．特に，ブリュッセル自由大学との共同研究を推進し，宇宙物質を高濃度で含む世界各地の衝突イジェクタ層を対象として，強親鉄性元素組成・オスミウムおよびクロム同位体比データを同一試料から取得する．これにより，地球史を通じて飛来してきた宇宙物質の起源を明らかにし，天体衝突と生命進化・絶滅の関連性を解読する研究へと発展させる．

    顕生代には地球への宇宙塵フラックス（流入量）が突発的に増加するイベントが知られており，それらと大量絶滅との関連性が指摘されている．しかし宇宙塵フラックス増加の原因や地球環境に与える影響については，ほとんど何もわかっていない．本研究では，顕生代における宇宙塵大量流入イベントの頻度や原因を高精度の同位体分析からつきとめ，その増加がどのような環境変動を引き起こしたのかを全岩化学組成の多変量解析から解明する．本研究を基礎として，宇宙塵フラックスの増減が，過去の地球環境や生命の歴史にどのような影響を与えてきたのかといった全く新しい研究展開が期待できる．
