Abstract
The Ba'yin copper deposit is a middle-sized ore deposit occurring in the western Tianshan mountain of Xinjiang.Ore bodies of the mine are hosted by intermediate to basic volcanic rocks and semimetal rocks.The concentrating of mineralization is dominated by the composite factors such as strata、structures and intrusive rocks.The study on rock-chemistry、inclusion geochemistry and stable-isotopic geochemistry indicates that the ore matter was origin in Upper Silurian System itself but imposed and transformed by magmatic hydrothermal fluid in Hercynian Period and the copper deposit is a stratibound deposit superimposed and transformed by mesothermal to epithermal hot water.
