1Ophiolites of the Central Asian Orogenic Belt:Geochemical and petrological characterization and tectonic settings显示文摘We present a compilation of published data(field,petrography,ages and geochemistry)from 73 ophiolitic complexes of the Central Asian Orogenic Belt.The ophiolitic complexes,ranging in age from Neoproterozoic to Triassic.have been geochemically classified as subduction-related and subductionunrelated categories applying recent,well-established discrimination diagrams.The subductionunrelated category is further subdivided into Mid-Ocean Ridge type(MOR),a common rift-drift stage and Plume type,and the subduction-related category is subdivided into Backarc(BA),Forearc(FA).Backarc to Forearc(BA-FA)and Volcanic Arc(VA)types.The four subduction-related types define highly different geochemical features,with the BA and FA types defining end members showing subduction influence of 10%-100%and 90%-100%subduction influence,respectively,and the two other types(BAFA and VA)define values between the two end members.The subduction-related category comprises79%of the examined ophiolites,of which the BA type ophiolites is by far the dominant group,followed by the BA-FA type,and with FA and VA types as subordinate groups.The Neoproterozoic and Ordovician complexes exhibit the highest,whereas those of Silurian age exhibit the lowest subduction-influence.Of the remaining 21%subduction-unrelated ophiolites,the MOR type dominates.Both the subductionrelated and subduction-unrelated types,in particular the latter,are commonly associated with alkaline basalts taken to represent ocean island magmatism.Harzburgite,dunite,gabbro and basalt are the common lithologies in all ophiolite types,whereas the BA-FA,FA and VA types generally contain intermediate to felsic rocks,and in the FA type boninites occur.The subduction-related ophiolites types generally show low metamorphic grade,whereas greenschist.amphibolite and blueschist grades occur in the subduction-unrelated and BA types.The highly different subduction contribution(from 0 to 100%in the MOR and FA,respectively),attest to variable dips of the subducting slab,as well as variable flux of subduction-related elements into the mantle above subducting slabs,from where the ophiolite magmas got their geochemical fingerprints.As most MOR ophiolites get subducted to the deep mantle,the subduction-related ophiolites have become a dominant ophiolitic type on Earth’s surface through all times supporting the idea about the early start of Plate Tectonics.Harald Furnes Inna Safonova 2019Geoscience Frontiers2019,10,4:15
2Triggers and sources of volatile-bearing plumes in the mantle transition zone显示文摘The paper discusses generation of volatile-bearing plumes in the mantle transition zone(MTZ) in terms of mineral-fluid petrology and their related formation of numerous localities of intra-plate bimodal volcanic series in Central and East Asia.The plume generation in the MTZ can be triggered by the tectonic erosion of continental crust at Pacific-type convergent margins and by the presence of water and carbon dioxide in the mantle.Most probable sources of volatiles are the hyclrated/carbonated sediments and basalts and serpentinite of oceanic slabs,which can be subducted down to the deep mantle.Tectonic erosion of continental crust supplies crustal material enriched in uranium and thorium into the mantle,which can serve source of heat in the MTZ.The heating in the MTZ induces melting of subducted slabs and continental crust and mantle upwelling,to produce OIB-type mafic and felsic melts,respectively.Inna Safonova Konstantin Litasov Shigenori Maruyama 2015Geoscience Frontiers2015,6,5:4
3The Russian-Kazakh Altai orogen:An overview and main debatable issues显示文摘The paper reviews previous and recently obtained geological,stratigraphic and geochronological data on the Russian-Kazakh Altai orogen,which is located in the western Central Asian Otogenic Belt(CAOB),between the Kazakhstan and Siberian continental blocks.The Russian-Kazakh Altai is a typical Pacific-type orogen,which represents a collage of oceanic,accretionary,fore-arc,island-arc and continental margin terranes of different ages separated by strike-slip faults and thrusts.Evidence for this comes from key indicative rock associations,such as boninite-and turbidite(graywacke)-bearing volcanogenic-sedimentary units,accreted pelagic chert,oceanic islands and plateaus,MORB-OIB-protolith blueschists.The three major tectonic domains of the Russian-Kazakh Altai are:(1) Altai-Mongolian terrane(AMT);(2) subduction-accretionary(Rudny Altai,Corny Altai) and collisional(Kalba-Narym) terranes;(3) Kurai,Charysh-Terekta,North-East,Irtysh and Char suture-shear zones(SSZ).The evolution of this orogen proceeded in five major stages:(i) late Neoproterozoic-early Paleozoic subduction-accretion in the Paleo-Asian Ocean:(ii) Ordovician-Silurian passive margin;(iii) Devonian-Carboniferous active margin and collision of AMT with the Siberian continent;(iv) late Paleozoic closure of the PAO and coeval collisional magmatism;(v) Mesozoic post-collisional deformation and anarogenic magmatism,which created the modern structural collage of the RussianKazakh Altai orogen.The major still unsolved problem of Altai geology is origin of the Altai-Mongolian terrane(continental versus active margin),age of Altai basement,proportion of juvenile and recycled crust and origin of the middle Paleozoic units of the Gorny Altai and Rudny Altai terranes.Inna Safonova 2014Geoscience Frontiers2014,5,4:3
4CO2加氢催化剂Cu/ZrO2/SiO2上Zr(IV)表面位对甲醇生成速率的影响(英文)显示文摘Cu/ZrO2/SiO2是有效的CO2选择加氢制甲醇催化剂.为了理解混合氧化物基催化剂中ZrO2的作用,在Cu和Zr的K边进行了原位X-射线吸收光谱测试.在反应条件下, Cu保持金属态,而Zr以三类配位环境的形式存在:体相ZrO2,配位饱和的、以及不饱和的Zr(Ⅳ)表面位.配位不饱和Zr表面位可通过线性拟合参比的X射线吸收近边结构光谱进行定量,发现其数量与甲醇生成速率有关,因而表明Zr(Ⅳ)Lewis酸表面位在驱动选择生成甲醇反应中的重要性.这与提出的机理是一致的:在裂解H2的Cu纳米颗粒与稳定反应中间体的Zr(Ⅳ)表面位之间的界面上进行CO2加氢.Erwin Lam Kim Larmier Shohei Tada Patrick Wolf Olga V.
