遥感技术能以较低的成本快速地提供更多更有效的地质异常信息，提高工作效率，降低风险[1]。在分析云南省北衙金矿远景区区域地质背景和控矿规律的基础上，通过目视解译的方法对该区的区域地质进行了解译，并对该区域进行详细的定量分析以及蚀变异常的光谱反映特征提取。从ETM影像中利用相关方法提取了与矿区有关的羟基、铁染异常信息，解译效果良好，划分了找矿远景区。%Remote sensing technology is quite an effectively to lower costs ,provide more abnormal geological information quickly,improve work efficiency and reduce the risk.Based on analysis of gold far scenic area and ore controlling regularity in the geological background of Beiya in Yunnan province ,interpretation can be obtained through visual of regional geology,the analysis and alteration can be achieved from spectra of detailed quantitative anomaly characteristics.From the ETM images u-sing extraction and mining related method of hydroxyl,iron related with abnormal information,interpretation of good effect, divided the prospecting area.
