摘　　要：文章在分析青海卡尔却卡地区矽卡岩型铜多金属矿床成矿地质条件及控矿因素的基础上,利用WorldView-Ⅱ高分辨率影像进行地质解译和Aster影像蚀变信息提取,总结了矽卡岩型矿床控矿要素的影像特征,构建了矽卡岩型铜及多金属矿床遥感找矿模型。依据找矿模型和遥感解译信息,在卡尔却卡地区预测了找矿远景区,为该区进一步找矿勘查提供了依据。Based on geological condition and ore-control factors of Cu-polymetal deposit in Kaerqueka area geological interpretation of WorldView-II image and extraction of alteration information are carried to summarize image feature of the ore-control elements and build model of remote sensing prospecting of Cupolymetal deposits in the area.According the prospecting model and the interpretation target areas are predicted to provide evidence for further prospecting in the area.
