| 摘 要： | 华南地区白垩纪-古近纪断陷红盆发育,在空间和时间上与热液型铀矿床关系密切,尤其是花岗岩体外带上覆盆地型铀矿床。文章通过综合分析断陷红盆中铀矿床的成矿地质背景、矿床地质特征,结合区域大地构造演化,探讨了该类型铀矿床的成矿模式及找矿标志。

Geological Features and Metallogenic Model of Granite-peripheral Uranium Deposits in Overlying Basin in South China |
| |
| Abstract: | Faulted-down red basins of Cretaceous and Paleogene are extensively distributed in South Chi-na. The faulted-down red basins is close related to hydrothermal uranium deposits in time and apace. In this paper,the geological background and features of uranium deposits in faulted down red basins were analyzed synthetically. Prospecting indicators of this type uranium was discussed after studying their geo-tectonic evolution and the metallogenic model. |
