摘　　要：在下庄铀矿田湖子地区发现有硅化带型、交点型及碱交代型铀矿化,并且以硅化带型铀矿化为主。深部钻探揭露显示,6009号硅化断裂带主带及其上盘次级构造带内的铀矿体在深部延伸比较稳定。在6009号硅化断裂带与黄陂-张光营辉绿岩组的深部交汇区内发现隐伏的缓倾斜铀矿体,该矿体严格受平缓断裂构造控制,根据已有地质成果与认识,推测铀矿体往深部延伸有变厚变富的趋势。深部隐伏缓倾斜铀矿体的发现,有望使湖子地区铀矿化点扩大成为中-大型铀矿床。Uranium mineralization in Huzi area of Xiazhuang orefield includes silicification zone type,intersection type and alkali metasomatism type,and the main type is silification zone type.Through deep drilling project,it was found that orebodies in the main silicification zone 6009 and sub-strcuture in its hanging wall extends stably to the deep,and gently inclined concealed orebodies were discosed in the intersection of 6009 silicified structure zone and Huangpi-zhangguangying dolerite groups.The concealed orebodies are strictly controlled by gently fracture.Acording to the known geology recognition and study result,the orebodies are deduced to be thicken and richen with deep extention.The discovery of concealed orebodies may be expected to change the uranium mineralization prospects in Huzi area to an middle-large deposit.
