摘　　要：运用多光谱(ETM)和高分辨率(Radarsat-2)遥感数据定量提取与矿化有关的构造、泥化蚀变、铁化蚀变遥感信息,结合地质、化探异常,将构造、铁化蚀变、化探异常叠合呈预测综合图。结合已知矿点地质特征,总结找矿标志,对工作区金多金属找矿潜力进行初步评价,圈定出4个找矿靶区。The remote sensing information such as structures, clay alteration and iron - stained alteration relating to the gold mineralization were quantitatively extracted by using ETM ＆ RAdARSAT- 2 remote sensing data in the selected Handeni study area. In combination with geological and geochemical anomalies, the integrated prospecting prediction maps were drawn which overlay the structures, iron- stained aheration and geochemical anomalies. Based on the known gold deposits （occurrences）, the metallogenic regulities are summarized and the preliminary evaluation of the prospecting potential in the Handeni area was conduted, four prospecting targets were outlined for the further exploration.
