| 摘 要： | 位于阿拉善台隆西北部的某盆地,是一呈EW向延伸的封闭盆地,盆地内冲积扇体系发育,主要沉积下白垩统新民堡群,局部有中下侏罗统地层。铀矿主要产于下白垩统新民堡群中岩组,扇前洼地亚相内的灰绿色细粒砂岩及泥质粉砂岩中。根据地质、水文地球化学环境等特征,结合成矿地质条件分析,认为盆地内铀成矿条件不利于形成具工业意义的铀矿,在有利层位及相带中可形成小规模铀矿。

| Abstract: | A certain U-deposit is located in a basin,north-western part of Alashan platform,which is a EW-striking enclosed basin,where developed alluvial-fan system,deposited Lower Cretaceous Xinminpu Group,Middle-Lower Jurassic strata partially.U-deposit mainly exist in the grayish green fine-granular silt-stone and argillaceous sand stone of depression sub-face before alluvial fan,the middle petrofabric of Lower Cretaceous Xinmingpu Group.By analyzing the features of geology,hydrochemical environment and metallogen... |
