摘要
湖子地区位于NNE向诸广—新兴铀成矿带与近EW向大东山—漳州大断裂复合部位,是华南早、晚两期铀成矿热液活动叠加区、放射性高场区,既有"硅化带大脉"型铀矿产出,又有"交点"型铀矿存在,找矿前景良好。文章在论述下庄矿田铀成矿地质环境、铀成矿特征及铀矿定位条件基础上,分析了湖子地区铀成矿条件与找矿前景,指出该区今后铀矿找矿方向是:①6009号硅化断裂带,在其北段找硅化带大脉型铀矿,在其南段找"交点"型铀矿;②新桥—下庄硅化断裂带和6009号带之间成矿部位,寻找硅化带型和"交点"型铀矿;③NW向、近EW向辉绿岩脉与NNE向、NE向构造交汇部位(交点),寻找"交点"型铀矿。
Huzi area is located at the intersection of NNE Zhuguang-Xinxing U ore belt and EW Dadongshan-Zhangzhou deep-seated fault and overprinted with the early and late hydrolhermal ore fluids. In the high radioactive field area occur both of the big silieifieation vein type and the intersection type U deposits and the area is potential for further exploration. This paper analyses metalogenie condition and ore potential of Huzi area based on geological setting, characteristics and locating condition of the U ore deposits and points out the further ore-searching direetion:①No. 6009 silieified fraetural zone whose north part is favorable for the big silieifieation type U ore deposit and whose south part for the intersection type;②the area between Xinqiao-Xiazhuang silieified fralural zone and No. 6009 silieified fraetural zone where is favotale for silieified zone type and intersection type;③interseetion of NW and near EW diabase dykes and NE straeture where is favorable for intersection type.
