摘　　要：以 1∶1 0万区域化探扫面资料为基础 ,以寻找火山岩型金矿为出发点 ,研究新疆白山地区地质地球化学成矿特征 ,并总结火山岩型金矿找矿标志。研究表明 ,金为主要成矿元素 ;二叠系、石炭系为金成矿有利层位 ;区域地球化学异常元素组合存在 4种类型 ,其中以Au ,As,Sb等元素为主的组合异常范围广、规模大 ,受断裂构造控制 ,主要呈带状分布于东西向断裂 (F2 )及其与F4断裂交汇部位。这些部位也是寻找火山岩型金矿的有望地段。Based on the 1∶100 000 regional geochemical data,looking for volcanic gold deposit,the regional geological and geochemical characteristics are studied with a summary of prospecting criteria of volcanic gold deposit and prediction.It is believed that Au is chief ore-forming element.Carboniferous and Permian favour gold mineralization.There are five kinds of element associations in the regional geochemical anomaly.The major associate anomaly of Au As and Sb distributes in large scope and is controlled by trending fault.The anomaly distribution bounds EW trending fault(F2) and the intersection between EW(F2) and NE trending fault(F4) in zonation,the best area to find volcanic gold deposits.
