摘　　要：下庄矿田湖子地区的铀矿体主要赋存在6009号硅化断裂带及其上盘次级构造带内,铀矿化以硅化带型为主,铀矿体产状陡倾;由钻探工程揭露,新发现的缓倾斜铀矿体位于6009号硅化断裂带与黄陂—张光营辉绿岩带的交汇区域,且具有较好的连续性,铀矿体产状缓倾,产状55°～65°NW∠17°～25°,矿体严格受平缓断裂控制,呈多层状分布,深部隐伏缓倾斜铀矿体的发现,有望使得湖子地区发展成为中—大型规模铀矿床。The uranium ore bodies are mainly forming in silicated fault belt of No. 6009 and its top of sub-structure. The uranium mineralization is a silicated zone type. The uranium ore body discovered recently is located in the intersection of silicified fracture zones of No. 6009 and dolerite zone of Huangpi-Zhangguangying. The ore body has a good continuity and attitude of 55° - 65° NW ∠ 17°-25°. Furthermore, the ore body is controlled by gentle fracture, and distributed with muhi-layers. The discovery of blind uranium ore body with gentle tilt in deep provide possible to find large-midium scale uranium in Huzi.
