【摘要】 对江西相山铀矿田内断裂构造格架及火山构造特征做了研究,认为相山火山盆地和断裂构造的成生与发育受永丰-抚州深断裂演化控制。从构造控矿作用看,相山铀矿田受大型中心式塌陷火盆控制,北部的EW向断裂带和中西部的EW向构造断陷带控制着矿田内的矿集带,NE向与EW向断裂构造复合部位控制了矿床的位置,密集成群的断裂裂隙带控制着铀矿体,使各矿床中的铀矿体呈群脉型。这些铀矿田地质构造特征及控矿规律对进一步找矿具有重要的指导意义。更多还原

【Abstract】 This study focuses on fault patterns and volcanic structures of the Xiangshan uranium ore-field in Jiangxi Province. The results suggest that the generation and development of the Xiangshan volcanic basin and faults are controlled by the three-step evolution of the Yongfeng-Fuzhou deep fault.From structural ore-controlling,the Xiangshan uranium ore-field is determined by large central-type collapse basins. The EW trending fault zone in north and the EW striking fault-depression belts in middle and west control the mineralization belts in the ore field. The conjoining part of NE and EW trending faults determines the position of ore deposits. Dense swarms of fracture and fissure zones control the uranium ore bodies,so that the uranium ore bodies in each ore deposit show a cluster-vein type. These structural characteristics and ore controlling rules of the Xiangshan uranium ore-field have significance for further prospecting.更多还原
