| 摘 要： | 华南地区基底铀背景值较高,区域热液铀矿形成于晚中生代-古近纪(K-E)的地壳拉张期。区内各类型热液铀矿床在成矿时代、温压条件、矿物组合及热液蚀变等方面有一定的共同特征,根据热液铀矿床的分布可划分为三大成矿带。铀成矿与伸展构造关系密切,且成矿流体、物质可能为不同来源;铀成矿期铀主要以碳酸铀络合物形式运移。 |
| 关 键 词： | 华南热液铀矿 成矿共性 伸展构造 成矿模式 |

| Abstract: | There is relatively high uranium background in the basement rocks in South China.Hydrothermal uranium deposits in this region were formed during crust extension period from late Mesozoic to early Tertiary.There are certain extent common features in mineralization time,p-t condition,mineral association and hydrothermal alteration for various kinds of hydrothermal uranium deposits in the region.Three mineralization zones have been divided based on the distribution of the hydrothermal uranium deposits.The uranium mineralization is closely associated with the extensional structures,but the ore-forming fluids and uranium could be from different sources.Uranium was transported mainly in form of uranyl carbonate complex. |
| Keywords: | hydrothermal uranium deposits in South China common features in mineralization extensional structures metallogenic model |
