| 摘 要： | VMS deposits in Xinjiang, NW China are widespread in the Altay, Tianshan and WestKunlun orogenic belt, mainly formed during the Proterozoic rifting and Phanerozoic post-orogenicextension and are related to the bimodal volcanism. The VMS deposits are middle and small inscale. According to assemblages of metallogenetic elements, they can be divided into four types(Cu-Zn, Cu-S, Pb-Zn-Cu and Pb-Zn types) with the Cu-Zn and Pb-Zn types being the most impor-tant ones. Research of isotopic chronology shows that the VMS deposits in Xinjiang were formedduring the Proterozoic, Ordovician, Deovonian, Carboniferous and Permian periods and usuallyunderwent multi-stage mineralization, especially the large-sized deposits usually have post-volcanic superimposed mineralization by tectonomagmatic or metamorphic hydrothermal metal-logenic fluids.

Research of isotopic chronology shows that the VMS deposits in Xinjiang were formed during the Proterozoic, Ordovician, Deovonian, Carboniferous and Permian periods and usually underwent multi-stage mineralization, especially the large-sized deposits usually have post- volcanic superimposed mineralization by tectonomagmatic or metamorphic hydrothermal metal- logenic fluids. |
