摘　　要：为促进内蒙古苏莫查干敖包地区铀矿找矿工作,应用卫星遥感数据开展蚀变异常信息提取和构造解译。根据ASTER遥感数据不同波段的波谱特征和典型蚀变矿物光谱曲线,通过主成分分析等方法提取了铁染、 Mg-OH/CO32-、 Al-OH等矿化蚀变信息;利用高分二号数据,初步厘定了工作区3级线性构造的遥感地质特征。在综合分析地质、遥感和地球物理等多源地学信息的基础上,圈定苏莫查干敖包铀成矿预测远景区,取得了良好的找矿效果,为当地铀矿勘查工作提供参考依据。In order to make a promotion of uranium exploration in Sumoqagan Obo, Inner Mongolia, remote sensing was used tor geological interpretation and alteration anomaly iniormation extraction. According to the different bands characteristics of ASTER data and spectral curves of typical altered minerals, the alteration information such as ferric contamination anomalies, Mg-OH/CO32 aleration anomalies and Al-OH aleration anomalies was extracted qualitatively by principal component analysis method. GF-2 remote sensing data was used to interprete line structure in three levels . Based on the analysis of multivariate geological data such as geology, remote sensing and geophysical, uranium prospecting target was delineated, which laid a solid toundation tor turther uranium exploration in the region.
