| 摘 要： | 本文通过对华南铀成矿地质环境和成矿条件的分析，指出华南铀成矿时代集中分布于50－90Ma，成矿作用与晚中生代红盆、产铀花岗岩体和含还原性物质的岩层在空间上关系，可与澳大利亚元古宙不整合型铀矿床对比；进而总结了华南中生代不整合型成因模式；并探索性地提出了其找矿标志和找矿方向。 |
| 关 键 词： | 中生代 不整合型铀矿档 成因模式 找矿标志 成矿时代 找矿方向 |

| Abstract: | This paper, through analyses of the geological settings and ore-forming conditions of the uranium deposits in South China, points out that the metallogenetic epoch of uranium ranges from 90-50 Ma, and that the ore-forming is closely related to Late Mesozoic red basins, granite bodies and reduced-material-bearing layers. It is correlated with the Proterozoic unconformity-related uranium deposit in Australia. Then a generalization of the metallogenetic model of Mesozoic unconformity-related uranium deposits is made, and the prospecting criteria and orientation are suggested. |
| Keywords: | unconformity-related uranium deposit metallogenetic model prospecting criteria |
