摘要
东城铀矿位于水口山–九嶷山铀成矿带内,铀矿主要受古岩溶和向斜构造、断裂构造联合控制明显,矿物质来源主要为二叠系含铀地层,褶皱构造、断裂构造及古岩溶构造为含铀地下水迁移和富集沉淀提供良好通道和赋矿空间。本文通过对矿区地质特征、矿体特征及成矿地质条件进行综合研究,认为该矿床属碳硅泥岩–淋积型铀矿床,并指明了矿标志。
Dongcheng uranium deposit is located in Shuikoushan Jiuyishan uranium metallogenic belt. The uranium deposit is obviously controlled by paleokarst, syncline structure and fault structure. The mineral source is mainly Permian uranium bearing strata. Fold structure, fault structure and paleokarst structure provide good channels and ore bearing space for uranium bearing groundwater migration and enrichment sedimentation. Based on the comprehensive study of the geological characteristics, ore body characteristics and metallogenic geological conditions of the mining area, it is considered that the deposit belongs to carbonaceous siliceous mudstone leaching uranium deposit, and the ore marks are pointed out.
