摘　　要：简要介绍巴音塔拉凹陷蚀源区岩石及年代学特征,论述了含矿地层特征、沉积物源、铀矿化类型、成矿年龄及铀成矿条件等。指出下白垩统含矿地层物源好,地质演化历史对后生水成铀矿有利,是寻找地浸砂岩型铀矿值得重视的地区。A brief introduction was made on the lithological and source regions, by studying the characters of ore-bearing chronological characters of rocks in stratum and its source, uranium mineralization type and age and the uranium metallogenic conditions and so on in Bayintala depression. The author suggests that ore-bearing strata of Lower Cretaceous have favorable uranium source and geological evolution process for the formation of epigenetic hydrogenic uranium deposit. Therefore, Bayintala depression is the favorable target area for searching in-situ leaching sandstone-type uranium deposit.
