| 摘 要： | 南岭地区是我国很重要的铀矿产地,该区是否存在前震旦纪基底一直的是研究的热点。本在大量野外调查和室内分析的基础上,厘定了南岭地区前震旦纪基底的存在,详细论述了前震旦纪基底地层——寻乌岩组的地球化学特征,分析了寻乌岩组成岩环境及其对铀成矿的贡献,为南岭地区富大铀矿的寻找提供依据。

| Abstract: | Nanling is one of the most important regions of the occurrence of uranium deposits. The question "if there exists the pre-Sinian basement" has been being the hot spot of geologic research in this region. On the basis of significant field observation and indoor analysis,this paper has determined that there does exist the pre-Sinian basement in Naling region,and detailedly expounds the geochemical characteristics of the pre-Sinian basement, the Xunwu Formation,and analyses the petrogenic environment of Xunwu Formation and its contribution to uranium ore-formation providing a basis for locating rich-large uranium deposits in Nanling region. |
