| 摘 要： | 通过对四川盆地龙潭向斜区域地质背景、找矿目的层侏罗系沙溪庙组和遂宁组地层特征、砂岩岩性岩相发育特征及地球化学特征的研究，笔者认为，目的层内灰色砂体发育，黄色砂岩为其蚀变产物。通过对砂岩型铀矿化特征的研究，综合分析了该区砂岩型铀矿成矿条件，认为该区具有较好的铀成矿环境和找矿前景。

| Abstract: | Based on the study of regional geology, stratigraphic characteristics, lithologic-lithofacies and geochemistry of the target horizon sandstone in Shaximiao and Suining formation of Jurassic were studied, it is concluded that the gray sandtone bodys had been developed and oxygenated to yellow sandstone in part. The characteristics of uranium mineralization and metallogenic conditions for sandstone type uranium deposits have been comprehensively analyzed in this paper. It is suggested that the metallogenic environments in the area are favourable and it has good prospecting potential. |
