摘　　要：四川省西北部是我国岩金矿床分布的重点地区之一,尤以微细浸染型金矿床为主.该区有刷经寺联合村、嘎拉、金木达等大中型与超大型金矿床,充分显示出金矿成矿的良好前景.在对区域成矿规律及成矿条件的认识基础上充分利用遥感技术,建立了以NW、E-W及近S-N向为主的区域构造格架,优化了蚀变信息提取方案.结合区域化探特征建立了区域遥感及地球化学综合找矿模式.综合区域遥感、地质、化探信息,利用GIS进行了预测选区.Northwest Sichuan is one of the significant regions for primary gold deposits in China,especially for the fine disseminated type of gold deposits.The distribution of middle,large and super-large gold deposits,such as Shuajingsi Lianhecun,Gala and Jinmuda,indicates a great potential for gold mineralization in this area.Based on the regional metallogenic law and ore-forming conditions,using remote sensing technology,the regional structural framework in NW,E-W and near S-N directions is established.The abstraction of alteration information is optimized.A regional remote sensing exploration model is built.With integrated information of remote sensing,geology and geochemical exploration,the target areas are forecasted by GIS.
