| 摘 要： | 通过野外地质调查、岩相学、地球化学和电子探针等分析方法,初步查明了修武盆地下寒武统黑色岩系中的铀矿物主要为磷钙铀矿和含磷钙钛铀矿,且多数以独立矿物形式存在,矿物颗粒微小,约1~3μm,少量与钛矿物共生;黑色岩系沉积受海底热液影响,其物源来自陆地和海底热水沉积物,由两者混合组成,且以陆源为主;铀的富集与碳、磷等元素关系密切。

| Abstract: | Based on the field geological survey, petrographic study, element chemical analysis and EP- MA, etc. It was found that uranium is enriched in the bone coal in the lower Cambrian black rock series of Xiuwu basin. Uranium minerals is mainly existed in form of phosphurancalcilite and phosphorus-contai- ning brannerite of which most are independent mineral with the size about 1-3 μm, and some grows a- round the edge of titania. Due to the affluence of hydrothermal fluid to seafloor deposition, the prove- nance of black rock series, is composed of terrestrial and submarine hydrothermal sediments which is mainly terrestrial . The enrichment of U element is closely related to the accumulation of C, P and other elements. |
