摘　　要：为了更准确地指示层间氧化带砂岩型铀矿的空间位置,从成矿特点出发探讨了金属活动态的异常形成机制,认为指示元素在弱氧化带为高异常,还原带为低异常,铀矿通常位于高异常向低异常过渡的区间内。以和什托洛盖盆地为例,综合分析了沉积相特征和铀源条件,认为研究区西侧的铁厂沟花岗岩体具备较好的铀源条件,铀元素自南西向北东方向迁移;在此基础上依据金属活动态的异常模式划定了成矿远景区。In order to accurately determine the spatial position of the interlayer oxidation zone sandstone type uranium deposits, the abnormal formation mechanism of metal active state was discussed based on the metallogenic characteristics ,that indicator elements in weak oxidation zone is shown as high anomaly, reduction zone as low anomaly, uranium deposit usually located in the transition between high anomaly and low anomaly. Taking heshi- tuoluogai basin as example, the characteristics of sedimentary facies and uranium source was analyzed, think the Tiechanggou granite in the west side of the study area has good uranium source conditions, uranium transport from south west to north east, and metallogenic prospect area was divided based on anomaly pattern of metal active state.
