摘　　要：利用江苏省1:20万区域化探资料,结合中大比例尺化探普查成果,运用GIS技术,提取剥蚀程度、相似度和衬值等地球化学信息,结合成矿带不同成因类型铜矿找矿模型,建立长江中下游成矿带(江苏段)铜矿地球化学定量预测模型,并进行铜矿预测区圈定、分级和铜矿资源量估算,为该矿带铜矿勘查工作部署提供了依据。This work is based on the 1：200 000 regional geochemical survey data and medium-large scale geochemical survey data in Jiangsu Province. We adapted the GIS technique to extract geochemical information such as erosion extent, similarity and contrast value, and established a quantitative geochemical prediction model of the copper deposits in this area, in combination with different oreprospecting models of various types of copper deposits. Furthermore, we carried out the delimitation, classification and assessment of copper ore prediction areas, which may provide basis for the deployment of copper resource exploration in this metallogenic belt.
