粤北南雄盆地热液型铀成矿地质特征及控矿因素

Geologic Feature and Ore-controlling Factors of Hydrothermal-type Uranium Ore Formation of Nanxiong Basin in North of Guangdong Province

南雄盆地内铀矿床众多,按成因分类有热液型、沉积成岩型、淋积成岩型铀矿床分布,分析阐述了热液型铀矿床的岩相古地理、成矿构造、矿体特征、围岩蚀变等成矿地质特征,探讨总结了热液型铀矿床的主要控矿因素,提出下一步铀矿找矿方向。

There are many uranium ore deposits in Nanxiong Basin.In accordance with the genetic classification,there are hydrothermal type,sedimentation and diagenetic type,and illuviation diagenetic type distribution.The paper analyzes and describes ore formation geological characteristic like the lithofacies paleogeography,ore formation structure,ore body characteristics,and wall rock alteration,etc.of hydrothermal uranium ore deposit.It summarizes the main ore controlling factors of hydrothermal uranium ore deposit,and puts forward the next prospecting direction of uranium ore deposit.
