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 the analysis of the metallogenic geological conditions and ore-controlling factors of skarn-type Cu polymetallic deposits in the Karzaka region of Qinghai Province, the geological interpretation and Aster image alteration information extraction using WorldView-Ⅱ high resolution images are summarized Skarn deposit ore-controlling elements of the image features, the skarn-type copper and polymetallic deposits remote sensing prospecting model. According to the prospecting model and remote sensing interpretation information, the Prospecting Prospecting Area is predicted in Karlka region, which provides a basis for the prospecting exploration in this area.
