摘　　要：针对金子山—铜厂地区地质背景较复杂,地形起伏较大,传统的找矿方式需突破等问题,利用ALOS多源遥感数据对该区进行了遥感地质解译,确定了该区域的岩性、线性构造、环状构造,色异常特征;并利用ETM+数据进行了主成分分析,提取了该区蚀变遥感异常信息,对各类遥感地质特征进行综合分析,提出研究区遥感地质找矿新方向。The Jinzishan- Tongchang area in Shaanxi Province is characterized by complexed geological background and rugged terrain conditions,which results in the difficulty to make the prospecting breakthrough by the traditional exploration method. Therefore,applying RS technology will be an effective approach for finding the deposits. In this study,the geological interpretation was carried out based on multi- source remote sensing data,such as WorldView- Ⅰ、ALOS and ETM＋,such as regional lithology,linear structures,circular structures and color anomalies etc.. Also,the altered information and anomalies were captured by applying PCA method based on ETM^＋ data. By the integrated analysis of extracted geological characteristics,new prospecting direction was proposed for the future exploration work.
