Abstract:
The uranium ore in Xiangshan of Jiangxi is one of volcanic-related meso-epithermal deposits, and the ore-controlling characteristic of fault structure is significant. Ore-controlling tectonic analysis and tectonic ore-controlling regularity were studied in Shannan mining area of Xiangshan uranium ore-field in order to provide scientific guidance for ore-prospecting in blind ore deposit. Field detailed observation and measurement showed that the main ore-controlling structures in Shannan mining area including NNE-and EW-NWW-trending fault fracture zones had experienced compressional in early stage and later extensional to tran-extensional broken deformation, and therefore were favorable for uranium deposited. The rule of ore-controlling fault was discussed, and it was suggested that the output characteristic of uranium ore-body was mainly controlled by the property of fracture zone. Additionally, the output characteristics of uranium ore-bodies in various rocks could be interpreted as the different deformation behaviors under tectonic stress, which could be helpful for understanding so-called lithologic ore-controlling. According to the regional ore-prospecting model with characteristic and regular pattern of ore-controlling structure, the preferred favorable sections included the southwest section of Hengjian deposit, joint of Gangshangying, Hengjian and Shimashan deposits, etc. More attention should be paid to high-grade ore-bodies probably in the intersection of NNE- and EW-NWW-trending faults and the sinistral dislocation of ore-body affected by the activity after the metallogenic epoch of NNE-trending fault.
