| 中文摘要: |
| 为分析下辽河盆地西部斜坡区砂岩型铀矿成矿地质条件,本次研究通过收集整理下辽河盆地以往地质勘查资料,利用煤田钻孔资料的“二次开发”,结合野外地质调查及能谱测量工作,对盆地的铀源条件、盆地构造及“补—径—排”体系、目的层条件等进行了分析,认为下辽河盆地西部斜坡区砂岩型铀矿成矿地质条件良好,其中明化镇组是成矿最有利层位；在控矿因素研究基础上,圈定了欢喜岭—盘山、大虎山—大民屯两个砂岩型铀矿成矿远景区,为进一步勘查提供思路。 |
| 英文摘要: |
| In order to analyze the geological conditions of sandstone-type uranium deposits in the western slope area of the Lower Liaohe Basin, this study analyzes the uranium source conditions, basin structure and “fill-diameter-row” system conditions, purpose stratum conditions, etc. of the Lower Liaohe Basin, by collecting and collating the previous geological exploration data of the Lower Liaohe Basin, using the “secondary development” of coalfield drilling data, and combining field geological survey and energy spectrum measurement, believe that the metallogenic geology conditions of sandstone-type uranium deposits in the western slope area of the Lower Liaohe Basin are perfect, and the Neogene Minghuazhen Formation is the most favorable mineralization layer for sandstone-type uranium deposits in this area. Based on the study of ore-controlling factors, two sandstone-type uranium metallogenic prospects, Huanxiling-Panshan and Dahushan-Damintun were delineated, and this can provide ideas for further exploration. |
