摘要
尖山铜矿位于塔里木板块觉罗塔格晚古生代沟弧带南缘,赋矿地层为下石炭统白鱼山组,含矿岩性为安山质凝灰岩.矿体受康古尔塔格深大断裂之分支断裂苦水大断裂形成的低序次层间断裂破碎带控制,矿体形态为细长脉状.近矿围岩蚀变主要为绿帘石化、绿泥石化、阳起石化、黄铁矿化及绢云母化等,成因类型为中-低温热液石英脉型.
Jinshan copper mine is located South Juelaotage latePaleozoic trenchisland arc belt of Tarim plate, The copper mine is produced in the andesitic tuff formation of the below Carboniferous Baiyushan Formation. It is controlled by the sub-class fault of Kushui big distributive fault derived by Kuguertage big fault, ore body is slightness nervation. It＇s near minerals wall rock alteration include epidotization,chloritization, actinolitization ,pyritization ,sericitization and so on. The genetic type belong epithermal middle-low temperature quartz vein copper mine.
