| 摘 要： | 基于GIS平台,通过对巴音戈壁盆地地质、物探、化探、遥感等多源信息进行综合处理分析,选取了化探铀、航放铀、遥感羟基等15个信息图层,采用证据权重法对研究区进行了铀成矿预测与评价,对预测结果进行分级,圈定了11个铀成矿远景区,取得了较好的效果,提高了研究区成矿预测的精确度与可靠性。

| Abstract: | Former data and information in geology,geophysics,geochemistry and remote sensing of Bayingobi Basin are processed and analyzed.Fifteen information layers such as uranium of geochemical survey,uranium of airborne radioactive survey and hydroxy anomaly of remote sensing are selected to assess and evaluate the uranium mineralization potential by the method of evidence weighting based on GIS.The potential areas are classified and 11 prospecting targets are delineated. |
