华南古岩溶铀矿床的矿物学特征为：表生矿物发育，原生成矿矿物少见；矿化脉体几乎没有；矿石中铀主要呈吸附状态，其次呈显微和超显微沥青铀矿存在。与古岩溶有关铀矿床则出现典型低中温热液矿物组合，矿化脉体期次分明，矿石中铀基本呈可见状沥青矿存在，沥青铀矿具有热液成因标型。鉴于该类矿床成矿前主岩溶为冷水成因，而热液成矿流体是与岩溶无关的体系，故属古岩溶热液叠造成矿
The mineralogical characteristics of the paleokarst karst uranium deposits in South China are as follows: epiphytic mineral development is rare, primary ore-forming minerals are rare, mineralization veins are scarce, uranium is mainly adsorbed in ore, followed by microscopic and ultra-microscopic uranium deposits. The uranium deposits related to the ancient karst appear typical low-medium temperature hydrothermal mineral assemblages. The mineralization veins are distinct and distinct. The uranium in the ore is basically visible asphaltic ore, while the uranium ore has the hydrothermal formation type. In view of the fact that the former karstification of this type of deposit was the cause of cold water and the hydrothermal ore-forming fluid is unrelated to karstification,
