新疆阿克陶县木基西铜矿地处天山南脉与昆仑山脉汇结处,区域大地构造属布伦口—普西亚—慕士山古断隆带西段海西期木吉—布伦口构造岩浆岩带。研究区与铜矿化有关的围岩蚀变为“退色”蚀变,发生在石英闪长岩与二长花岗岩接触带外带,蚀变带岩石呈碎裂结构、块状构造,遭受强烈的动力变质作用,受热后组分发生碎裂现象,原岩成分和结构构造严重破坏,硅化、绢云母化强烈。矿床受构造控制明显,推测为受构造控制的岩浆和热液后期改造型铜矿床。
Xinjiang Akto County Muji West Copper Mine is located at the convergence of the southern Tianshan Mountains and the Kunlun Mountains, the regional tectonic belonged to Burenkou-Puxiya-Mu Shi Mountain western section of the ancient fault belt Kyrgyzstan Kyrgyzstan - Bulunkou Structural magmatic belt. The wall rock alteration related to copper mineralization in the study area is “fading ” alteration, occurring in the belt of contact zone between quartz diorite and monzogranite. The alteration zone rock is fragmented and massive structure, suffered Strong dynamic metamorphism, the components after heating fractured phenomenon, the original rock composition and structural damage, silicification, sericitization strong. The deposit is controlled by the tectonism and is presumed to be controlled by tectono-tectonic magma and hydrothermal late-typed copper deposit.
