摘要: 为了探讨鄂尔多斯盆地北东部塔然高勒地区砂岩型铀矿成矿地质条件，通过分析该地区的地质构造、岩相–岩性特征、古气候、古水文及铀源等条件，采用煤田资料筛查、地质编图等方法对其细致进行了研究。经过综合分析后认为，塔然高勒地区中侏罗统直罗组下段放射性异常发育，为主要找矿目的层；直罗组下段砂体厚度适中，砂体顶、底板隔水层发育稳定，存在有利成矿的“泥–砂–泥”地层结构，具备有利成矿的岩性–岩相条件，同时铀源丰富，具有较好的成矿前景。
Abstract: In order to investigate the ore-forming geological conditions of sandstone-type uranium deposits in the Taran Gaole area (the eastern part of the Ordos Basin, China), the stratigraphic structure, lithology-lithographic conditions, hydrology, paleoclimatic and uranium sources in this area were analyzed, and the methods of coalfield data screening and geological mapping were used to study the geological conditions. After comprehensive analysis, it is believed that the radioactive anomalies in the Lower Section of the Middle Jurassic Zhiluo Formation in the Tarangaole area are abnormally developed, which is the main target layer; the thickness of the sand body in the Lower Section of the Middle Jurassic Zhiluo Formation is moderate, the top and bottom layers of the sand-soil are stably exist, and the “mud-sand-mud” stratigraphic structure which is favorable for ore-forming, shows necessary lithology-lithographic conditions. In addition, uranium sources are relatively abundant. Therefore, it has a better metallogenic prospect.
