在分析二连盆地额仁淖尔凹陷区域地质、构造及水文地质条件的基础上,对区内地下水进行了水文地质动力分带、构造-古水文地质分期及深层地下水特征的研究,确定了两个重要的铀成矿期。用同位素水文学及同位素单孔示踪技术揭示了含矿含水层地下水的补给、径流、排泄条件及水动力机制;用水文地球化学研究指出了苏崩及努和廷铀矿床所处位置均为地下水性质的强烈变异部位,并确定了找矿指示元素。用有机地球化学研究探讨了油气运移及地下水与铀成矿作用之间的关系,表明区内油气上逸对铀成矿起了重要作用。研究结果提出下白垩统巴彦花群腾格尔组中可能存在适合于地浸开采的层间氧化带型砂岩铀
Based on the analysis of the geology, tectonics and hydrogeological conditions of the Neerrenal Sag in the Erlian Basin, the hydrogeological dynamic zonation, structural-paleogeological geologic staging and deep groundwater characteristics of the groundwater in the area were studied. Two Important uranium mineralization period. Using isotope hydrology and isotopic tracing techniques, the recharge, runoff and discharge of groundwater in the aquifers and the hydrodynamic mechanism are revealed. The hydrogeochemical studies indicate that the locations of both the Supu and Nuhenting uranium deposits are Strong variations in the nature of groundwater and the identification of elements for prospecting. The relationship between hydrocarbon migration and groundwater and uranium metallogenesis was explored by organic geochemical study, indicating that the uplift of oil and gas plays an important role in uranium metallogenesis. The results suggest that there may exist intergranular oxidation zone sandstone uranium in the Lower Cretaceous Bayanhua Tenggeer Formation
