摘　　要：研究区地处西南三江成矿带南段,是寻找铜多金属矿产的潜力地区。为在大平掌铜矿区外围寻找具有类似成矿地质背景的远景区域,从遥感地质的角度上,利用ASD Field Spec 3便携式光谱辐射计对区内与矿化密切相关的硅化、绿泥石化、褐铁矿化等蚀变信息进行波谱信息采集,基于实测波谱反射曲线采用光谱角分类法对ASTER数据提取各类遥感矿化蚀变信息。结合遥感地质解译成果和地质矿产资料进行找矿信息分析,为该区矿产勘查提供遥感支撑。The study area is located in the southern section of the southwest Sanjiang metallogenic belt,and is a potential area for looking for copper polymetallic minerals. In order to found the prospect area with similar metallogenic geological background of Dapingzhang copper deposit in the outside area,from the view of remote sensing geology,using ASD Field Spec 3 portable spectral radiometer to collect silicification,chloritization,limonite spectral information which is closely related to mineralization in the area. Mineralization information can be extracted from ASTER remote image using the method of spectral angle classification,based on the measured spectral reflection curve. It is carried out that for exploration information analysis combining with the results of remote sensing geological interpretation and geological minerals data,which support mineral exploration by remote sensing.
