摘　　要：卡尔却卡地区隐爆角砾岩型铅锌矿位于柴达木盆地西南缘,金、铅、锌(铜、稀有、稀土)成矿带(Ⅲ12)(为伯喀里克-香日德印支期)处于该带的最西侧区域上,侵入岩(中酸性)在该区大量的发育,金水口岩群基地岩系具有非常高的固结程度,也是最为古老的,区内历经非常复杂的地质演化,构造运动在该区非常的强烈。发育的构造行迹具有较好的力学性质与不同规模,该区的主体构架是压扭性断裂(北西西向)所组成,严格控制着区内的变质作用以及岩浆岩和分布的不同地层,矿产形成明显受控于该断裂,找矿前景非常的优越。The cryptoexplosive breccia type lead-zinc deposit in karqueka area is located in the southwest margin of Qaidam Basin.The gold,lead,zinc (copper,rare and rare earth) metallogenic belt (Ⅲ12) (the berkerik Xiangride Indosinian period) is located in the westernmost part of the belt.The intrusive rocks (intermediate acid) are developed in this area.The base rock series of Jinshuikou group has a very high degree of consolidation and is also the most developed It is an ancient area with complex geological evolution and strong tectonic movement in this area.The developed structural traces have good mechanical properties and different scales.The main framework of the area is composed of compression and torsion faults (Northwest West direction),which strictly controls the metamorphism,magmatic rocks and different strata in the area.The formation of minerals is obviously controlled by the faults,and the prospecting prospect is very good.
