英文摘要	The Sartohay chromitite deposit, hosted in the Sartohay ophiolite melange in western Junggar (Xinjiang province, NW China), contains irarsite, breithauptite, and Fe-Ni-As-S minerals. Petrographic observations indicate that the chrome-spinel was firstly altered to Fe-rich chromite at low-temperature with relatively lower Fe3+/Fe2+ ratios (0.14-034), and such Fe-rich chromite was altered to magnetite in a relatively oxidizing environment. Afterwards, irarsite, breithauptite, and Fe-Ni-As-S minerals formed during hydrothermal processes. A systematic change from magnetite-pentlandite, pentlandite-heazlewoodite-maucherite, millerite-breithauptite, to millerite-godlevskite-irarsite-dominated assemblage in the Sartohay chromitites suggests a complex evolutionary path in the P-T-fS(2)-fO(2) space. Enrichments of Os, Ir, Sb, and As in disseminated irarsite, breithauptite, and Fe-Ni-As-S minerals reflect the mobility of Os, Ir, Sb, and As during low-temperature hydrothermal processes overprinting the chromitites in the Sartohay ophiolitic melange.
