玉门昌马金矿金的富集特征

摘要

玉门昌马金矿赋存于北祁连造山带西段与阿尔金走滑断裂交汇部位,严格受SN向车路沟断裂控制。经历了3次成矿地质作用,形成沿走向及倾向都呈＂S＂形的石英脉型金矿。文章总结了该矿床的地质和围岩蚀变特征,对矿床富集特征进行了分析探讨。%Changma gold deposit is situated at the intersection part between north Qilian orogenic belt and Altun strike-slip fault,controlled by NS Chelugou faults NS.Structure and magma activity provides a heat source for gold mineralization and storage enrichment
