摘　　要：通过收集西大明山铅锌矿田成矿带地质、遥感、已知矿点等资料,利用TM遥感图像处理技术,在假彩色合成及比值假彩色合成图像上提取与铅锌矿成矿有关的构造、围岩蚀变信息,并在TM图像上地质解译出线性、环形构造,将所获得的多种遥感信息进行复合。结合该区域已知资料,综合圈定出5个成矿远景区,为西大明山地区进一步开展矿产资源调查工作提供了基础资料和科学依据。Through the collection of data related to geology, remote sensing and known mineral occurrences in metallogenic belts of Xidamingshan Pb-Zn ore field, and through the application of the TM remote sensing image processing technology, this paper extracted information of the structure and wall rock alteration related to the genesis of Pb-Zn deposits from false color composite image and false color composite ratio image. The author made geological interpretation of linear and circular structure out of TM images, and recombined a variety of remote sensing information. Based on the known information of this area, this paper blocked out five metallogenic prospect areas and provided basic data and scientific basis for further investigation of mineral resources inside Xidamingshan area in the future.
