摘　　要：文章以TM多光谱遥感数据为基本信息源,从实际地质情况出发,采用计算机识别和人工判读相结合,对区内的线形、环形构造进行了解译。应用比值+主成分分析的方法对区内热液弱蚀变信息进行了提取。在此基础上,综合利用已知矿床的分布以及遥感构造信息、遥感蚀变晕信息,结合已有的物化探资料,分析出4个找矿远景区。Taking TM multi - spectrum remote sensing data as the basic information source, using computer combination of computer recognition with artificial distinguish, this paper interprets linear and ring structures in the Gejiu mining district. Weak hydrothermal alteration information is extracted using ratio plus main component analysis method. Four ore - searching prospecting areas are pointed, based on known ore deposit distribution, remote sensing structure and alteration halo information, and obtained geophysical and geochemical exploration information.
