摘要
巴音铜矿是位于新疆西天山的一个中型铜矿床。矿化体赋存于中基性火山岩及沉积岩中,矿化富集受地层、构造、侵入岩多重因素控制。岩石化学、包裹体地球化学和稳定同位素地球化学特征研究表明,成矿物质来源于上志留系本身,但遭受了华力西期岩浆热液的叠加-改造。该矿床为中-低温热液叠加改造型层控矿床。
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.
