摘　　要：多元地学信息GIS集成与融合分析应用于找矿的实例较少,它可以实现元素地球化学系列数据处理与分析工作,为成矿预测提供找矿靶区信息。结合冷水坑地区多元地学信息GIS集成与融合分析应用实例,对单元素、多元素地球化学场进行了综合分析,信息表明,在冷水坑地区存在一个多元地学信息环形构造,根据环形构造圈定了4个寻找隐伏银铅锌多金属矿的远景区,并在小源远景区(即银珠山矿区)寻找到一个大型银铅锌多金属矿,为区域成矿预测提供了科学依据,并提高了隐伏矿的预测效果。Multiple geo-information,GIS,integration and fusion analysis have been insufficiently used in ore-prospecting work;nevertheless,with these means,we can conduct data processing and geochemical analysis and provide more information for ore-prospecting targets.Exemplified by multiple geo-information work in Lengshuikeng area based on GIS application,integration and fusion analysis of single element and multi-element geochemical fields,this paper deals briefly with the integration of multiple GIS and geo-information fusion method.The result obtained shows that in Lengshuikeng there exists a multivariant geological information ring structure,based on which four prospective areas of concealed lead-zinc polymetallic deposits were delineated,and a large-size silver-lead-zinc polymetallic deposit was found in Xiaoyuanj prospective area（Yinzhushan ore district）.These achievements provide scientific basis for regional ore prognosis and improve the effect of predicting concealed ore deposits.
