为了在西华山地区铜矿调查工作中缩小矿产勘查范围，进一步指明铜矿勘查方向，以调查区构造形态和矿化蚀变带为研究对象，利用现代遥感技术，选取法国Spot5和美国陆地卫星ETM为遥感信息提取数据源。采用面向特征主分量选择法（克罗斯塔技术）进行蚀变信息提取，并利用目视解译法结合光谱特征，对调查区线、环构造和区域地层岩性进行遥感解译．在本次解译结果和蚀变信息提取的基础上，通过对调查区区域构造特征、成矿条件的详细分析表明，遥感影像线环构造明显，可以有效区分岩性、提取地层与隐伏构造信息。区内铜矿化与线性构造关系十分密切，矿化体多受北东一南西向断裂控制，东南部具有良好的找矿前景．最终利用解译信息编制了线环构造解译图，并成功圈定成矿有利地段，为该调查区铜矿调查工作奠定了坚实的基础．

In order to narrow the exploration area and specify the exploration direction in Xihua mine survey, structure and mineralizing alteration are taken as the research object in the survey area by using remote sensing technology to extract the alteration information. French Spot5 and land satellite ETM of USA are selected as the data resource, and the primary method of alteration information extracting is Feature Orientated Principal Component Selection (Crosta technique). Visual interpretation method and Spectral characteristics are combined to interpret structure and formation lithology of survey area. Based on this results and alteration information extracting, structure and condition of mineralization are analyzed in details on survey area, result indicates that the structure in the remote sensing image is obvious to distinguish lithology, information of Stratum and Concealed structure, and there is close relationship between the Chalcocitization and the line structure, mineralized bodies are controlled by NE-SW trending fault. Finally, structure interpretation map and contouring of ore favorable area are drawn with interpretation information, and mineralization favorable position is successfully delineated, it is foundation for copper mine survey in the future.
