摘要
以济源盆地中生代侏罗系为研究对象,分析探讨了研究区中生代盆地物源及水动力、铀源、构造、沉积环境及沉积建造、铀成矿层位和矿化特征。研究表明:该区铀矿为典型的滨浅湖相层间氧化带沉积砂岩型铀矿,初步推断其形成主要经历了盆地含矿建造形成和铀初次聚集阶段、表生-后生富集成矿阶段和岩浆热液叠加改造阶段,侏罗系杨树庄组为该区主要的含铀层位,具有重要的找矿潜力和研究价值。为该区域铀矿勘查提供了一定的参考依据。
The provenance,hydrodynamic condition,structure,sedimentary environment and formation of the Jiyuan basin are discussed,as well as the source of uranium and its mineralized position and mineralization characteristics. It is a typical sandstone-type uranium ore deposit of the interlayer oxidation zone formed in the shore and shallow lake. Three stages are put forward,that are the first gather of uranium with the formation of basin and ore mine construction,supergene and epigenetic mineralization,superposition reconstruction caused by magmatic hydrothermal. It has potential and valuable advantages for the prospecting uranium of Jurassic Yangshuzhuang Formation which is the main uranium-bearing position in the research area. Some references can be provided for the prospecting uranium ore in the research area.
