Autor: Peng-Fei Zhang, Mei-Fu Zhou, Paul T. Robinson, John Malpas, Graciano P. Yumul, Christina Yan Wang, Jie Li

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-12 (2024)

Abstract Ophiolites, mostly formed via subduction initiation at proto-forearcs, exhibit a unique variation of mantle-derived magmatism from MORB-like to low-Ti tholeiitic and bainitic-like affinities. Such variation was suggested to form chromite dep

Trace Elements in Chromite as Indicators of the Origin of the Giant Podiform Chromite Deposit at Kempirsai, Kazakhstan

Autor: Wen-Jun Hu, Mei-Fu Zhou, Marina A. Yudovskaya, Ilya V. Vikentyev, John Malpas, Peng-Fei Zhang

Publikováno v: Economic Geology. 117:1629-1655

This study presents a complete trace element data set of chromite from the world’s largest podiform chromite deposit at Kempirsai, Kazakhstan, together with platinum group element (PGE) and Re-Os isotope compositions, to explore the potential of tr

Constraints of Fe-S-C stable isotopes on hydrothermal and microbial activities during formation of sediment-hosted stratiform sulfide deposits

Autor: Fang Huang, Mei-Fu Zhou, John Malpas, Xiao-Chun Li, Wenhong Johnson Qiu

Publikováno v: Geochimica et Cosmochimica Acta. 313:195-213

Microbial and hydrothermal venting activities on the seafloor are important for the formation of sediment-hosted stratiform sulfide (SHSS) deposits. Fe isotopic compositions are sensitive to both microbial and hydrothermal activities and may be used

High-Ca boninitic melt inclusions in lavas of the Troodos ophiolite and a reappraisal of genetic relationships between different lava types

Autor: Zhong-Yuan Ren, Mei-Fu Zhou, John Malpas, Wen-Jun Hu

Publikováno v: GSA Bulletin. 133:1831-1850

Boninites in many supra-subduction zone ophiolites are thought to mark the early stage of subduction. The Troodos ophiolite in Cyprus contains a variety of volcanic rocks including the lower pillow lavas and the boninite-bearing upper pillow lavas (U

Modification of mantle rocks by plastic flow below spreading centers: Fe isotopic and fabric evidence from the Luobusa ophiolite, Tibet

Autor: Yongsheng He, Mei-Fu Zhou, Qiong-Ying Liu, John Malpas, Paul T. Robinson, Peng-Fei Zhang

Publikováno v: Geochimica et Cosmochimica Acta. 253:84-110

Combined Fe isotopic and olivine fabric analyses have been conducted on the nodular chromitites from the Luobusa ophiolite, Tibet, to study the physico-chemical effects of plastic flow in modifying chromitites and their associated mantle peridotites

Evolution of nascent mantle wedges during subduction initiation: Li-O isotopic evidence from the Luobusa ophiolite, Tibet

Autor: Peng-Fei Zhang, Mei-Fu Zhou, Julian A. Pearce, Paul T. Robinson, John Malpas, Xiaoping Xia, Qiong-Ying Liu

Publikováno v: Geochimica et Cosmochimica Acta. 245:35-58

The Li-O isotopes of olivine and pyroxene from the mantle sequence of the Luobusa ophiolite, a fragment of Neo-Tethyan forearc lithosphere in Tibet, reveal a series of magmatic processes and geochemical evolution in a nascent mantle wedge during subd

Origin of high-Cr chromite deposits in nascent mantle wedges: Petrological and geochemical constraints from the Neo-Tethyan Luobusa ophiolite, Tibet

Autor: Mei-Fu Zhou, John Malpas, Peng-Fei Zhang, Paul T. Robinson

Publikováno v: Ore Geology Reviews. 123:103581

The petrography and compositions of chromitites and peridotites from the Tibetan Luobusa ophiolite, a fragment of Neo-Tethyan forearc lithosphere, are used to study the origin of high-Cr chromite deposits and relevant magmatic evolution in nascent ma
