摘　　要：本文在综述查干德勒苏盆地地质背景的基础上 ,阐述了盆地水文地质特征 ,并结合盆地地质演化史进行了古水文地质条件分析。根据层间氧化带砂岩型铀矿特征 ,从目的层空间展布、铀源、水文地球化学环境、水中微量元素、放射性水化学特征等角度提取了铀成矿信息 ,在盆地中部南缘圈定了一片铀成矿远景区。On the basis of comprehensively describing the geologic setting of the Zhagandelesu basin,this paper expounds hydrogeologic features of the basin,analyses paleohydrogeologic conditions of the basin in accordance with the geologic evolution of the basin,Based on the characteristics of interlayer oxidation zone sandstone-type uranium deposit,such as the spatial distribution of target horizon,uranium source,hydrogeochemical environments,concentration of trace elements in water,radioactive-hydrochemical features,etc.,uranium ore-formation information has been extracted,and a prospective area for sandstone-type uranium deposit has been delineated.
