    <title>Abstract</title>Recent studies have documented the occurrence of shallow very low frequency earthquakes (VLFE) in subduction zones. The heterogeneity of the materials or stresses that act on the plate interface results in the variable slip rate. Stress on the décollement can be controlled by the décollement geometry and the regional stress, which is also able to control the material properties. We determined the distribution of stress along the shallow portion of the décollement in the Nankai Trough using a three-dimensional (3D) seismic survey and regional stress analysis to construct maps of normalized slip tendency (<italic>T</italic><sub><italic>s</italic></sub>′) and dilation tendency (<italic>T</italic><sub><italic>d</italic></sub>).

  • Effect of mechanical stratigraphy on the structure and kinematics of salt-bearing fold-and-thrust belts: Insights from scaled analogue experiments with optical strain monitoring (digital image correlation)

    Feng, GM; Chen, SP; Adam, J; Yamada, Y; Wang, XP

    2D contractional scaled analogue experiments with composite materials including silica-sand and mica-flakes for overburden and silicone for salt analogue are used to investigate effects of mechanical stratigraphy on the structural evolution and kinematics of salt-detached fold-thrust-belts. Specific parameters tested are mechanical stratigraphy of the overburden and thickness variation of the basal silicone layer. The silicone-detached models in general are characterized by low-taper thrust wedge geometries and non-systematic vergence of folds and thrusts. Strain localization in the undeformed layer occurs as an in-sequence foreland breaking sequence. Strain is nucleating as detachment folds including thrust-bounded and concentric folds. Increased shortening develops break-thrusts in fold limbs. In-sequence frontal thrust interacts with out-of-sequence reactivation of older thrusts in the internal thrust wedge. Syn-kinematic silicone mobilization causes diapirism, allochthonous sheets and source-fed thrust. The specific distribution of discordant and allochthonous silicone structures vary with the mechanical stratigraphy. The impact of the mica-interlayer in the overburden sequence is strain-dependent. It strengthens the undeformed sand-pack compared to initial thrusting while active thrusts with mica-flakes in shear zones are weaker and active for longer than in homogeneous sand-pack. The longevity of thrusts correlates with the transfer of silicone to external domains and hanging-walls of thrusts. The silicone thickness controls the strain nucleation modes whether thrusting-dominated or folding-dominated predating main-thrusting stages. It also governs silicone supply and flow regimes with thick silicone source layers being readily remobilized to source-fed thrust and inflate silicone massifs in the foreland. Insights from the modelling results are that the formation of large-transport source-fed thrusts such as Quele Thrust (China) and Chazuta Thrust (Peru) observed in salt-bearing FTB's is possibly attributed to salt detachment thickness and anisotropic overburden resulting from mechanically layered stratigraphy.

  • Water permeability of sunlit lunar highlands regolith using LHS-1 simulant

    The regolith on the Earth's Moon has been attracting attention from the perspective of understanding the planetary surface processes and procuring in-situ resources. However, very few studies have investigated the hydraulic properties of the lunar regolith, which should pose one of the most significant physical properties for understanding the lunar surface processes and evaluating regolith utilizations. In this paper, we study the water permeability of the surficial regolith layer on sunlit lunar highlands using the lunar highlands regolith simulant LHS-1. We measure the water permeability of LHS-1 at packing fractions of 0.49–0.60 by simulating lunar gravitational environments and evaluating the influences of freeze-thaw, which is expected to occur on the sunlit lunar highland surfaces. Our results indicate that the water permeability of lunar highland regolith is one to two orders of magnitudes lower than that of fine silica sands and monodisperse spherical glass beads at the given packing fraction. The low water permeability of lunar highland regolith attributes to the regolith particles having irregular and angular shapes with sharp edges and micron-sized chunks due to the least weathering, unlike soil particles on the Earth. The horizontal water permeability of lunar highland regolith simulant before freeze-thaw is 1.6 × 10−13 m2 at a packing fraction of 0.6. From the porosity-depth profile available from previous studies, we also obtained the water permeability-depth curve, representing the vertical water permeabilities of 6 × 10−13–2 × 10−12 m2 and 7 × 10−14–3 × 10−13 m2 at the lunar surface and the depth of 5 m within the surficial lunar regolith layer, respectively. We also found that the water permeability of lunar highland regolith increased after one freeze-thaw cycle, achieving 6.4 times higher than the permeability before the freeze, and the increase was more significant with lower packing fractions. We suggest that the pore water in the solid phase due to the freeze encourages the rearrangement of the regolith particles changing the total contact area between the particles. This study will help us better understand the abundance and distribution of molecular water on the lunar surface, lunar surface processes, and regolith utilizations.

  • On the deposition and polymorphism of CaCO_3 crystals in the presence of the tetrapod-shaped ZnO nanomaterials and polydimethylsiloxane composite

    The calcium carbonate (CaCO_3) scale generated in water pipes and heat exchangers causes serious problems such as pipe blockage and corrosion. This study investigates the effect of the 4-to-10 μm-long and 350-to-700 nm centering-nucleus-wide ZnO tetrapod-like nanomaterials and polydimethylsiloxane composite (t-ZnO/PDMS) on deposition and polymorphism of CaCO_3 crystals on the stainless-steel substrate. The results showed that the t-ZnO/PDMS coating inhibited CaCO_3 depositions and represented an excellent antifouling coating. The weight-based inhibition efficiencies of CaCO_3 deposition were up to 81.3% and 63.2% at 20 °C and 60 °C, respectively. The t-ZnO/PDMS coating also exhibited good inhibition in the presence of liquid flow. The inhibition is primarily because the very fine concave-convex microstructure of the t-ZnO/PDMS coated surface lowered the surface energy of the substrates, making it difficult for CaCO_3 crystals to adhere to the surface. Also, metastable vaterite and aragonite precipitations were dominant in the t-ZnO/PDMS coated coupons at 20 °C and 60 °C, respectively, whereas the uncoated coupon exhibited calcite as the predominant polymorph in all the studied conditions. The t-ZnO/PDMS composite subject to the liquid flow made calcites distorted and framboidal vaterite aggregates, likely due to their mechanical effects. The inhibition of CaCO_3 depositions is due to achieving hydrophobicity on substrate surfaces, changing preferential polymorph formation, and tailoring the morphology of the given polymorph by the t-ZnO/PDMS composite.

    <p>立山黒部ジオパーク（以後，立黒）は，『高低差4000 mロマン　富山の中の地球へ行こう』をテーマにした，富山県東部の9市町村にまたがるジオパークである．日本海から北アルプスまで，43のジオサイト，40の文化サイト，28の自然サイトを有しているが，地形的特徴からジオサイトがなかなか見学に行けない山岳地帯に多い感は否めない．そのため市街地から近く，児童生徒の学習にも使え，手軽に見学できるジオサイトの開拓が望まれていた．　今回，富山県中新川郡立山町の中心部から車で15分程の稲村にある産廃場跡地を整備したところ，スランプ構造の全容が観察できる大露頭（南北約80 m，東西約70 m，高さ約30 mの範囲に内向き斜面の崖が「凡」字形に配列している）が出現し，それを一般公開することができた．ここに至るまでの主な経緯は，2000年頃：最初の地権者により採土場として掘削を開始．’05年：新上市町誌（新上市町誌編集委員会編，2005）に「折戸凝灰岩層，海底火山灰の堆積した緑色凝灰岩の地層」として，スランプ構造の写真が掲載される．’05－’10年？：現地権者が瓦の粉砕施設をつくり，稼働するも程なく中止．産廃場に使うがこれも中止．以後，遊休地．’21年2月：立黒のジオパーク再認定決定．審査員から身近なジオサイトの開発を望まれる．5月：立黒研究教育部会で予備調査を行い，巨大なスランプ構造が灌木と崖錐堆積物にかなり被覆されているものの，ジオサイトになりうると判断．6月：地権者に立ち入りの許可を得ると同時に，町役場にジオサイト化に向けて協力を要請．11月：役場担当から，露頭の学術的評価が欲しいとの要請で，立黒が保柳に現地調査を依頼．保柳から情報を得た荒戸，立黒学術顧問竹内章富山大学名誉教授も加わり現地調査．地元紙が露頭を写真入りで報道．’22年1月：荒戸がボーリングコア採取の許可を得たい旨．地権者との交渉をジオパークに依頼．同時に，荒戸が代表を務める『海底地すべりモデルの構築：日高沖「静内海底地すべり堆積体」の発生機構と運動様式』（科研費番号 19H02397）の研究チームに，当該露頭の調査研究を提案．立黒が地権者にボーリングコア採取を説明．許可を得る．4月：勉強会を実施し，崖錐堆積物を取り除けば，スランプの構造を立体的に研究できる大露頭が出現する可能性が議論される．5月：町民向け現地説明会の実施と地元紙，ケーブルテレビの報道．6月：現地調査を実施し，重機を使って整備工事を行い，研究を進めることを確認．これを受けて，立黒が地権者に調査方法を説明，実施の承諾を得る．7月：町役場に露頭整備にあたる業者の紹介を依頼し，それに基づき見積もりを徴取．8月：露頭の整備，調査，整備後の立黒の利用に関して，地権者，荒戸が所属する秋田大学，立黒で覚書を締結．9月：整備工事開始し，十日程で終了．その後，予備調査．ステップ設置，底面のトレンチの工事を追加で依頼．10月：チームでの調査．地元小学5・6年生全員が見学．11月：チームでの調査．分析用試料の採取．説明看板の内容の検討を開始．下旬にステップの撤去とトレンチの埋め戻し．12月：ワークショップの開催．解説看板の土台の設置．’23年4月：解説看板，安全ポールコーンの設置．同時に立入禁止の柵を撤去し，一般公開の開始．5月：立黒ジオガイド向け現地研修会の開催．調査は継続中．　露頭の調査開始から一般公開まで極めて順調であったは要因は，・科研費の一部を露頭整備に使用し，そのまま見学対象となった．・地権者との交渉や町役場と現場周辺住民への説明，調査前後の整備及び撤収作業の立ち合いは立黒が担当．・露頭が県道のすぐ脇にあり，駐車スペースも十分で，大型重機による作業が可能．・露頭整備を請け負った業者が現場から車で15分の距離で，高所作業車，発電機，排水ポンプ，高圧洗浄機など急な要望にも対応．・地権者との覚書の締結で，現場の大規模な改変が可能となる．　一方，残る問題点は，・すでに泥岩部が剥離し始めており，何もしなければ10数年で整備前の状態に戻ると思われるが，保全する費用の目処が立っていない．・以前の施設の残骸を撤去しきれていない．　ジオサイトにはその保全が求められるので，この露頭をジオサイトとして維持するためには，上記問題点の解消が必要である．謝辞：同地での調査と一般公開を快諾くださった英修興産有限会社と，調査作業諸事にご協力頂いた有限会社きんたに心より感謝申し上げます．文献：新上市町誌編集委員会編，2005，新上市町誌．上市町，921p．</p>

    <p>地質現象は、一般に規模や時間が人間にとって直感的に理解できる範囲を超えている。それを補うために、実験や数値シミュレーションを用いてスケールを変更する試みが行われてきた。中でも褶曲や断層などの変形に関する分野では、時間的にもサイズ的にも現象を縮小して再現することで、最終的な変形形態やその形成過程について理解するだけではなく、その知見を地下資源開発の探査と開発に役立ててきた。褶曲形成に関する理論化がほぼ完成され、それを解析する能力が十分に向上した1980年代には、褶曲変形に関する検討は数値シミュレーションで十分に行えるようになった。一方断層などの破壊に関する検討は、数値シミュレーションの制約が大きいことから主として物理実験によって検討が進められてきた。物理実験によって変形現象を縮小再現する際、現象の物理的な意味を保ったまま（つまり物理的等価に）縮小するための理論的な条件（相似則）は1950年代に完成していたが、その条件を満たすように実験を行うことは困難であった。しかし、2000年以降に微小物性を計測できる試験機が開発されたことに伴い、相似律を満たすように実験材料の物性を微調整することができるようになった。これを受けて、様々な地質環境における変形構造を物理的等価に縮小・再現する物理実験が可能となってきている。本講演では、Massaro et al 2021, Massaro et al 2023の成果を基に、縮小模型実験の可能性が広がりつつある状況を報告する。 Massaro, L., Adam, J., Yamada, Y. 2023.

  • Surface friction of subducting seamounts influences deformation of the accretionary wedge Reviewed International journal

    Undulating topography on a subducting oceanic plate causes substantial deformation of the accretionary wedge. In particular, the subduction of a seamount is considered to induce 1) the development of landward concave topography such as reentrant and indented features, 2) compression within the accretionary wedge, and 3) disturbance of the primary thrust-sheet structures by uplift associated with the formation of multiple faults. However, according to previous seismic profiles, some subducting seamounts have provided suggestive evidence for weak wedge deformation rather than strong compression and uplift that were indicated in the previous model experiments. As the cross-sectional shape of an accretionary wedge is known to be strongly constrained by the internal and basal friction of the wedge, this study evaluates the effect of the frictional conditions of a subducting seamount on the deformation of the upper plate using analog experiments of two seamount models with low and high friction, respectively. Results show that subduction of a high-friction seamount causes continuous compression and uplift of the accretionary wedge, with the plate boundary fault zone composed of discontinuous multiple faults that offset vertically and partially overlapped to form a thick deformation zone. In contrast, a low -friction seamount is associated with a relatively thin wedge and a single plate boundary fault, which results in less compression compared with a high-friction seamount. During the subduction of a low-friction seamount, the accretionary wedge grows locally as the thickness of sediment on the seamount decreases, which has not been reported in previous studies. The wedge deformation pattern around the subducting Bennett Knoll Seamount in the Hikurangi Margin could be explained by the mechanism observed in the low-friction seamount subduction. From these results, we conclude that the frictional conditions on the seamount surface are a dominant control on the process of wedge deformation during the early stages of seamount subduction.

    Abstract. The Oman Drilling Project (OmanDP), performed under theInternational Continental Scientific Drilling Program (ICDP), is aninternational scientific research project that undertook drilling at a range of sites in the Semail ophiolite (Oman) to collect core samples spanning the stratigraphy of the ophiolite, from the upper oceanic crust down to the basal thrust. The cores were logged to International Ocean Discovery Program (IODP) standards aboard the D/V Chikyu. During ChikyuOman2018 Leg 3 (July–August 2018), participants described cores from the crust–mantle transition (CM) sites. The main rock types recovered at these sites weregabbros, dunites and harzburgites, rocks typically forming the base of theoceanic crust and the shallow mantle beneath present-day spreading centres.In addition to the core description, selected samples were analysed by X-ray fluorescence spectrometry (XRF) for their chemical compositions, including major, minor and some trace elements. To complement these standard procedures, we developed newapproaches to measure ultra-trace element concentrations using a procedureadapted from previous works to prepare fine-grained pressed powder pelletscoupled with laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis using instrumentation aboard the D/V Chikyu. First, three (ultra)mafic reference materials were investigated to test and validate our procedure (BHVO-2, BIR-1a and JP-1), and then the procedure was applied to a selection of gabbro and dunite samples from the CM cores toexplore the limitations of the method in its current stage of development.The obtained results are in good agreement with preferred values for thereference materials and with subsequent solution replicate analyses of the same samples performed in shore-based laboratories following Leg 3 for theCM samples. We describe this procedure for the determination of 37 minor and (ultra-)trace elements (transition elements and Ga, Li and Large-Ion Lithophile Elements (LILE), Rare Earth Elements (REE), High-Field-Strength Elements (HFSE), U, Th, and Pb) in mafic and ultramafic rocks. The presented method has the major advantage that it allows the determination at sea of the(ultra-)trace element concentrations in a “dry”, safe way, without usingacid reagents. Our new approach could be extended for other elements ofinterest and/or be improved to be adapted to other rock materials duringfuture ocean drilling operations aboard the D/V Chikyu and other platforms.

    Completely carbonated peridotites represent a window to study reactions of carbon-rich fluids with mantle rocks. Here, we present details on the carbonation history of listvenites close to the basal thrust in the Samail ophiolite. We use samples from Oman Drilling Project Hole BT1B, which provides a continuous record of lithologic transitions, as well as outcrop samples from listvenites, metasediments, and metamafics below the basal thrust of the ophiolite. 87Sr/86Sr of listvenites and serpentinites, ranging from 0.7090 to 0.7145, are significantly more radiogenic than mantle values, Cretaceous seawater, and other peridotite hosted carbonates in Oman. The Hawasina sediments that underlie the ophiolite, on the other hand, show higher 87Sr/86Sr values of up to 0.7241. δ13C values of total carbon in the listvenites and serpentinites range from −10.6‰ to 1.92‰. We also identified a small organic carbon component with δ13C as low as −27‰. Based on these results, we propose that during subduction at temperatures above >400°C, carbon-rich fluids derived from decarbonation of the underlying sediments migrated updip and generated the radiogenic 87Sr/86Sr signature and the fractionated δ13C values of the serpentinites and listvenites in core BT1B.

    Detailed reconstruction of Indian summer monsoons is necessary to better understand the late Quaternary climate history of the Bay of Bengal and Indian peninsula. We established a chronostratigraphy for a sediment core from Hole 19B in the western Bay of Bengal, extending to approximately 80 kyr BP and examined major and trace element compositions and clay mineral components of the sediments. Higher delta O-18 values, lower TiO2 contents, and weaker weathering in the sediment source area during marine isotope stages (MIS) 2 and 4 compared to MIS 1, 3, and 5 are explained by increased Indian summer monsoonal precipitation and river discharge around the western Bay of Bengal. Clay mineral and chemical components indicate a felsic sediment source, suggesting the Precambrian gneissic complex of the eastern Indian peninsula as the dominant sediment source at this site since 80 kyr. Trace element ratios (Cr/Th, Th/Sc, Th/Co, La/Cr, and Eu/Eu*) indicate increased sediment contributions from mafic rocks during MIS 2 and 4. We interpret these results as reflecting the changing influences of the eastern and western branches of the Indian summer monsoon and a greater decrease in rainfall in the eastern and northeastern parts of the Indian peninsula than in the western part during MIS 2 and 4.

    Language：English   Publishing type：Research paper (scientific journal)  

    Microbial life inhabits deeply buried marine sediments, but the extent of this vast ecosystem remains poorly constrained. Here we provide evidence for the existence of microbial communities in similar to 40 degrees to 60 degrees C sediment associated with lignite coal beds at similar to 1.5 to 2.5 km below the seafloor in the Pacific Ocean off Japan. Microbial methanogenesis was indicated by the isotopic compositions of methane and carbon dioxide, biomarkers, cultivation data, and gas compositions. Concentrations of indigenous microbial cells below 1.5 km ranged from <10 to similar to 10(4) cells cm(-3). Peak concentrations occurred in lignite layers, where communities differed markedly from shallower subseafloor communities and instead resembled organotrophic communities in forest soils. This suggests that terrigenous sediments retain indigenous community members tens of millions of years after burial in the seabed.

  • Analogue and numerical modelling of accretionary prisms with a décollement in sediments

    <title>Abstract</title>Active accretionary prisms at subduction margins generally include a horizontal detachment, décollement, within the sedimentary pile. The décollement, and its extension to undeformed regions (i.e., proto-décollement), corresponds to a layer of high fluid pressure. The deformation of the prisms, including such an anomalous layer, can be modelled and examined using analogue experiments and numerical simulations. Both these methods approximate the material under deformation as an assembly of particles (grains). The décollement layer is found to be best modelled by intercalating a layer with smaller internal frictional coefficient than the surrounding materials corresponding to the sediments. Our analogue experiments with dry sand and microglass beads reproduce structural geometry similar to that of interpreted seismic profiles at the toe of the prisms. Thrust faults originate from the horizontal beads layer and propagate upward with a constant angle of about 30°. Each of the fault bends produces a series of minor back thrusts. A particle image velocimetry (PIV) analysis revealed that the fault activity is characterized by intermittent reactivation and segmentation. The numerical simulations based on the distinct element method (DEM) were performed with similar kinematic settings and material properties as the analogue experiments. The numerical simulation results not only reproduce similar geometries as in the analogue experiments, but also show that the particle assembly experiences temporal variations in the deformation velocity and stress field as deformation propagates. This might be related to stick-slip motion of the frictional fault surfaces, which is a common feature of faulting during accretionary processes at subduction margins.

    沈み込み帯縁辺の島弧や陸弧の地殻は，その発達過程において肥大化と縮小化の時期を繰り返すが，特定の時期に地殻が肥大化するプロセスはよく分かっていない．後期白亜紀は海嶺に接近にともなって大陸縁辺域の火成活動が活発化するとともに，付加体が大きく成長した時期でもある．本研究の目的は，沈み込み帯縁辺における活発な火成活動と隆起・削剥作用が島弧地殻を飛躍的に成長させることを実験的に検証することである．本研究では，西南日本の各地質体の岩石を用いて，後期白亜紀の火成活動及び隆起・削剥作用を検証する．また，多量の土砂が海溝に供給される時において帯状の地帯構造配列が形成される条件をアナログ実験から制約する．

Educational Activities

  • In order to change society for the better, I believe that researchers must be actively involved in educational activities. Since students studying at Kyushu University are expected to play an important role in an increasingly complex and international society after graduation, we are working to educate students so that they have the knowledge and skills to meet the expectations of society, as well as a multifaceted, international perspective and logical thinking.

    Specifically, through lectures, exercises and fieldwork, students are taught not only textbook knowledge and skills, but also the complexity of natural phenomena and how humans understand only part of them, how they are connected to other phenomena and global issues, and how the human space-time scale affects the process of perceiving them. The course also provides students with the opportunity to think about the relationship between global activities and human life. We also work with students on the links between global activities and human life, in particular the social and energy systems that underpin modern civilisation and the SDGs and ESGs.

    In recent years, due to the risks and costs of outdoor activities, education and research in the field have become increasingly difficult worldwide. In response to this, we are working on safe and efficient field education, incorporating technologies such as virtual fields, which are now being offered by overseas universities. In addition, we are using our experience of remote experiment research, which is being carried out in collaboration with companies, to seek better ways of conducting remote experiments and to make experimental education using cross-reality (XR) technology a reality.

    With the help of friends in various parts of the world, we are strengthening our collaboration with universities and institutions in Japan and abroad that are interested in environmental and energy issues, using schemes such as JICA and JOGMEC, and my position as a visiting professor at the University of London. At the same time, I am taking a more ambitious approach to human resource development programmes such as exchanges and training with high schools and companies, as well as publicity and promotional activities.
