郴州—钦州铀成矿带南西段铀成矿基本规律

The basic pattern of the uranium mineralization's southwest segment of Chenzhou￣Qinzhou uranium metallogenic belt

郴州—钦州铀成矿带南西段铀矿化类型多而杂,成矿成岩时差大。在成矿时间和空间分布上,表现为区域成矿时间的集中性,与区内燕山晚期伸展拉张的断陷期相吻合,不同类型的铀矿床是受伸展拆离的深大断裂统一控制的中低温热液铀矿床。铀源具多源性。

Uranium mineralization types at the southwestern segment of Chenzhou-Qinzhou uranium metallogenic belt is various and complicated. Because the formation time of the mineralizaion and granite is quite different. The mineralization formed in a narrow time gap which coincides with the faulted down period of the regional extension in Later Yanshanian. Different types of uranium deposit are low temperature hydrothermal uranium deposit which is controlled by the deep great fracture due to the spreading. There are many sources for the uranium mineralization.
