西滩金矿床位于塔里木板块北缘晚古生代火山岛弧带,属典型的浅成低温热液石英脉型金矿。矿床控矿构造为破火山口放射状和环状断裂系统。成矿流体主要由大气降水热液组成,其运动状态表现为沿较宽大断裂裂隙快速(上涌)流动。沸腾作用是主要的一种动力成矿机制,成矿方式以充填作用为主。成矿反应系统包含成矿反应、控制反应及缓冲控制反应3类,动力学条件对成矿起主导作用
The West Bank gold deposit is located in the Late Paleozoic volcanic arc belt on the northern margin of the Tarim plate, and is a typical epithermal quartz vein type gold deposit. Deposit ore control structure caldera radial and annular fracture system. The ore-forming fluid is mainly composed of hydrothermal fluid from the atmosphere, and its movement is characterized by rapid (upwelling) flow along the wider fracture. Boiling is the main kind of dynamic metallogenic mechanism, and the metallogenic method is mainly filling. The ore-forming reaction system includes three types of metallogenic reaction, controlled reaction and buffer-controlled reaction. The kinetic conditions play a leading role in metallogenesis
