摘要
通过对哈达图铀矿床矿体特征的研究,认为该矿床为赛汉组上段建造间古河谷砂岩型铀矿床,其矿床成因属于“渗入与渗出叠加型”,铀矿化具有“预富集—富集—迁移—再富集”的滚动富集特征,矿体的形成主要受铀源、构造反转、岩性-岩相、氧化带发育程度和还原残留体等关键要素控制,在分析这些关键控矿要素的基础之上,初步总结了哈达图铀矿床成矿模式。
Through the study of orebody characteristics of Hadatu uranium,this deposit was believed the sandstone type of paleo-valley between the upper member of Saihan Formation,the genesis falls into the“infiltration and seepage superposition”,the uranium metallization experienced the scroll enrichment of“pre-enrichment,accumulation,migration,enrichment”.The formation of the ore body were mainly controlled by uranium source,structure,lithology,lithofacies,oxidation zone and the residual of reduced sand body.Based on the analyzing of the key controlling factors,a metallogenic model was summarized in the primary for Hadatu uranium deposits.
