摘　　要：本文结合盆地的区域地质背景 ,分析了三塘湖盆地的盖层沉积构造特征、找矿目的层的空间展布、地下水“补 径 排”系统和层间氧化带发育特征 ,认为该盆地相对稳定 ,埋藏浅的斜坡带地段具备了层间氧化带砂岩型铀矿成矿环境 。Combined with the regional geologic setting,this paper analyses tectonic characteristics of cover sediments,the spatial distribution of prospecting target horizon,the recharge?runoff?discharge system of groundwater and suggests that relatively stable and shallow?buried slope zones in Santanghu basin possess basic metallogenic conditions for the formation of interlayer oxidation zone sandstone?type uranium deposits,and are worth further prospecting.
