【摘要】：玉华山地区是赣杭构造带西南段重要的铀矿找矿远景区之一,毗邻中国最大的火山岩型铀矿田——相山铀矿田。玉华山地区基底变质岩、岩浆岩、断裂构造、热液活动和铀矿化特征指示区内具有较大的找矿潜力。与相山矿田对比,两者成矿条件基本相同,但在火山活动、晚期热液活动强度、剥蚀程度等方面存在较大差异。玉华山地区地球化学与地球物理异常特征表明,区内U-Th-Mo化探综合异常、正负磁异常交替和放射性正异常等异常叠加区是铀矿勘查的重点区域。同时,在成矿条件、地球化学条件与地球物理条件的基础上,构建了研究区综合信息找矿模型,为区内铀矿勘查工作提供了理论与实践依据。笔者认为为山—筒山断裂带是今后资源量突破所在,建议部署相关勘探工程,查明铀资源量。
[Abstract]:The Yuhuashan area is one of the important uranium prospecting areas in the southwestern section of the Ganhang structural belt. It is adjacent to the Xiangshan uranium ore field, the largest volcanic type uranium ore field in China. The basement metamorphic rocks, magmatic rocks, fault structures, hydrothermal activities and uranium mineralization characteristics indicate that there is a great potential for prospecting in the Yuhuashan area. Compared with Xiangshan ore field, the metallogenic conditions are basically the same, but there are great differences in volcanic activity, late hydrothermal activity intensity, denudation degree and so on. The geochemical and geophysical anomalies in the Yuhuashan area indicate that the U-Th-Mo geochemical comprehensive anomaly, the alternating positive and negative magnetic anomalies and the positive radioactivity anomalies are the key areas for uranium exploration. At the same time, on the basis of metallogenic conditions, geochemical conditions and geophysical conditions, a comprehensive information prospecting model of the study area is constructed, which provides a theoretical and practical basis for uranium exploration in the study area. The author thinks that the Shanshan-Dengshan fault zone is a breakthrough in the future resources, and suggests to deploy the related exploration projects to find out the uranium resources.
