| 摘 要： | 通过对中棚岩体地球化学特征的研究,探讨其与铀矿化的关系。中棚岩体属于过铝质花岗岩,高钾钙碱性岩石系列。分析认为,岩体具有S型花岗岩特征,为陆壳物质部分熔融的产物,原岩可能为寒武系浅变质砂岩。构造环境判别认为,岩体属于后碰撞花岗岩范畴,在岩石圈伸展作用构造环境下由寒武系部分熔融所形成。岩体的原岩铀含量较高,为富铀的中棚岩体形成奠定了基础,也为后期成矿提供了充足的铀源。

| Abstract: | The geochemical characteristics of Zhongpeng pluton in Zhongshan region of south Hunan was studied in this paper.The geochemical characteristics showed that Zhongpeng pluton fall into the type of high potassium calcium-alkaline and peralumious series rocks and belong to the S-type granite in genesis which may derived from crustal matter by partial melting with the provenance of Cambrian metamorphose sandstone.Structure environment analysis suggested that the pluton belong to Post-COLG and formed under the extension tectonic setting.The uranium content of essentially stratum was high which laid the foundation for the uranium mineralization. |
