| 中文摘要: |
| 截至目前，石油、核工业等系统均在巴彦呼舒凹陷开展了调查评价工作，大致查明了凹陷的地质特征及成矿条件，并发现了较好的铀矿化线索。为梳理该凹陷铀矿化的控矿要素并开展远景预测，笔者对已有钻孔、地震等资料进行了分析总结，结合化验分析结果，认为该凹陷具备充足的铀源、发育扇三角洲平原等有利的沉积相带、具备较好的砂体，而且在构造作用下，沿西侧蚀源区发育大规模的潜水 -层间氧化，在总结控矿要素的基础上，圈定了找矿远景区 1处。 |
| 英文摘要: |
| Up to now，Geological investigation and evaluation have been carried out in the BayanhushuDepression by petroleum and nuclear industries. The geological characteristics and mineralization conditions of thedepression were roughly identified，and good clues of uranium mineralization were found. According to the data of boreholes，seismic data and laboratory analysis，the author believed that the depression has abundant uranium source，favorable sedimentary facies belt such as delta plain，and good sandbody，and large-scale phreatic water-interlayer oxidation developed along the west erosional source zone under tectonism. Further summarized the ore-controlling elements within the area and delineated one prospecting prospect area. |
