| 摘 要： | 基于ETM+遥感数据解译研究区地质构造，利用ASTER数据，采用光谱角填图法（SAM）提取矿化蚀变信息.同时，结合研究区化探异常数据分布特征、岩体的空间展布特征、已有的地质资料等，总结了研究区典型矿床的成矿地质规律，并达到了成矿模型要求.最后，在内蒙古东乌珠穆沁-满都地区进行了成矿远景区的圈定.研究结果表明：结合ETM+和ASTER遥感数据和化探异常数据，建立遥感成矿模型，在圈定成矿远景方面有一定的可行性，该方法值得进一步推广.

| Abstract: | The geological structures of the study area are interpreted on the basis of ETM+ data. The mineralized alteration information is extracted with spectral angle mapper (SAM) and ASTER data. Based on the previous geological data, combining the distribution characteristics of geochemical abnormal data with the spatially occurrence of rocks in the study area, the geological laws for metallogenesis of typical deposits are summed up to meet the requirements of metallogenic model. Finally, the prospective areas of mineralization in the Dong Ujimqin-Mandu region, Inner Mongolia, are delineated. The results show that the remote sensing mineralization model by combination of ETM+ and ASTER data with geochemical abnormal data is feasible to delineate metallogenic prospect areas. Practice has proved that this method is worthy of further application. |
