| 摘 要： | 在对平庄盆地地层、构造和盆地演化研究的基础上，认为该盆地白垩系孙家湾组、阜新组及九佛堂组地层具有形成地浸砂岩型铀成矿的地质条件：存在有利的岩性；砂体发育，呈泥-砂-泥互层结构；冲积扇相、河流相和三角洲-湖滨沼泽相是铀成矿的最有利岩相；盆地北部、东部蚀源区铀源充分；存在有利于形成层间氧化的构造条件.平庄盆地找矿目的层主要为孙家湾组，次为阜新组及九佛堂组，主要找矿类型为层间氧化带型.

| Abstract: | Based on the study of stratigraphy, structure and evolution of the Pingzhuang basin, it is considered that the Cretaceous Sunjiawan, Fuxin and Jiufotang formations satisfy the conditions to form in-situ leachable sandstone type of uranium deposits, such as the favorable lithology, developed sand bodies with mud-sand-mud interbedding structure, the favorable alluvial fan, fluvial and delta-limnetic facies, sufficient uranium sources in north and east of the basin, and favorable structure for interbed oxidation. The target horizon is Sunjiawan formation, followed by Fuxin and Jiufotang formations. The main prospecting type is interbedding oxidized zone. |
