| 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: | Located in the southwestern part of Gan-Hang tectonic zone and closed to the Xiangshan uranium orefield, the largest volcanic-type uranium orefield in China, the Yuhuashan area is a significant prospective prediction area for uranium ore deposit. In this paper, a systematic study of uranium metallogenic conditions such as metamorphic basement, magmation, fracture structure, and hydrothermal activity indicates that Yuhuashan area is an excellent potential area for uranium mineralizaiton. Compared with the Xiangshan uranium orefield, they have many great differences in such aspects as the degree of volcanic activity, the degree of late hydrothermal activity, and the denudation degree. The geochemical and geophysical anomalies of Yuhuashan area indicate that the area within the comprehensive anomaly of U -Th -Mo, the alternate magnetic positive and negative anomalies and positive radioactive anomalies are favorable areas for uranium exploration. Based on the ore-forming geological, geochemical and geophysical conditions, the authors established a comprehensive anomaly model and a uranium exploration model for Yuhuashan area, which will provide important theoretic and practical reference for uranium exploration in the future. Moreover, the authors hold that more exploration work should be preferentially carried out along the Weishan-Tongshan fault zone which is the key position of resource reserves. |
