  • The Changjiang uranium ore field, located in Renhua county of Guangdong province, is the most important granite-type uranium ore field in southern China. There developed the NNW-trending (nearly SN-trending) ore-bearing fault structures, NEE-trending Mianhuakeng fault and NWW-trending Youdong fault. Understanding the characteristics of the Mianhuakeng fault and the Youdong fault and their relation to uranium mineralization is conducive to the building of ore-controlling structure system and further prospecting for uranium deposits. We carried out detailed field investigations, and focused on the analysis of the correlation between the Mianhuakeng fault, Youdong fault and NNW-trending (nearly SN-trending) ore-bearing faults, especially the development characteristics of fault structures and their combination with each other. Our key findings are as follows. (ⅰ) The Mianhuakeng fault is a brittle fracture belt, characterized by uncemented tectonic breccia and fault gouge containing well-rounded granite rubbles. It has obvious linear structures and negative geomorphic features, belonging to a post-mineralization compresso-shear fault, and it dislocates uranium ore body and uranium mineralization zone with small displacement; (ⅱ) The Youdong fault is a brittle fracture zone with linear structures and negative landforms. It is a tensional-torsional fault associated with NNW-trending (nearly SN-trending) ore-controlling structure and partially filled by subsequent mafic dikes. It is not a high degree ore-controlling fault and only plays a role of local ore-bearing structure; (ⅲ) There are several small ductile deformations near the Youdong fault, not that they formed a continuous ductile deformation belt resulting from the Youdong fault, but that they are ductile deformations inner the Youdong granite body with small scale, different strike and sporadic occurrence. (ⅳ) Based on the distribution of NNW-trending (nearly SN-trending) ore-bearing fault structures, the further prospecting for uranium deposits should be not along the Meihuakeng fault and Youdong fault, but along the NNW-trending (nearly SN-trending) fault belt, concentrated on the strike extending area and dipping deep area. In the meantime, there is a good chance for concealed ore zone at the surface and shallow parts of the vacancy for prospecting between existing ore zones.
