摘　　要：新疆穷布拉克铜矿位于西天山阿吾拉勒山西段,矿床产于古生界二叠系之上、下二叠统不整合界面之内外侧的火山熔岩及沉积火山凝灰质砂砾岩中,具明显层控特征,矿体呈似层状、透镜状顺层产出,产状与地层基本一致。矿化富集与断裂及火山-次火山热液活动有关,主要矿体受近EW向穷布拉克断裂及其派生的次级裂隙带控制,矿床围岩蚀变较强烈,主要为绿泥石化、碳酸盐化。The Qionghulake copper deposit is located at west Alulale region in west Tianshan Mountains.It occurs in volcanic lava and sediment-volcanic tuffaceous sandstone and conglomerate in the inside and outside part of Paleozoic unconformity between upper and lower Permian system.It is obviously controlled by the strata.Mineralization enrichment is relative with faulting and volcanic and subvolcanic hydrothermal activity.The major orebodies are controlled by Qiongbulake fault and its sedimentary fault belts.Wallroek alteration is relatively might, such as chloritization and carbonation.
