青海祁连郭米寺-尕大坂铜多金属矿成矿地质特征和成矿模式探讨

The Qinghai Qilian Guomi Temple-Essential Osaka copper polymetallic deposit metallogenic geological characteristics and metallogenic model

青海祁连郭米寺-尕大坂铜多金属矿位于北祁连成矿带走廊南山成矿亚带．矿区主要出露中寒武统，其次为上石炭统及白垩系．含矿蚀变带长2500m，宽20～150m，最宽155m，向北西逐渐尖灭，向南东被白垩系巨厚红层和石炭系煤系层掩盖，已发现长800m，宽20-155m的含矿带．矿床成矿类型为典型的与海相中酸性火山活动有关的块状硫化物矿床（白银厂式矿床）．

The Qinghai Qilian Guomi Temple-Essential Osaka copper polymetallic deposit is located in the northern Qilian metallogenic belt corridor Nanshan metallogenic belt. Main mining area exposed in low er Cambrian, the second to the carboniferous, and cretaceous. Contain mineral alteration with 250m long and 20-150m wide, 155m wide, most pinchout gradually to the north west, south east is the cretaceous the thick red and carboniferous coal layer mask, have found 800m long and 20-155m ore belt width. Metallogenic types for typical related to Marine intermediate-acid volcanic activities of massive sulfide deposits （silver factory type ore deposit）.
