砂岩型铀矿化是在富铀古流体的作用下,使赋矿岩石产生粘土化、黄铁矿化及后期碳酸盐化等蚀变,并在特定的氧化-还原障处铀元素富集成矿。通过对后生蚀变岩石以及矿石矿物(如黄铁矿等)的相关同位素分析,不仅可以追踪古流体的成因或来源,而且还可以判定矿物(黄铁矿等)的形成期次,从而可以推断矿床所遭受古流体改造期次,对矿床成因作出更深
Sandstone-type uranium mineralization is under the action of ancient uranium-enriched fluid, which causes alteration of ore-forming rocks into clay, pyrite and later carbonation. At the specific oxidation-reduction barrier, uranium enrichment mine. The related isotope analysis of epigenetic alteration rocks and ore minerals such as pyrite can not only trace the origin or origin of paleo-fluid but also determine the formation period of minerals (pyrite etc.) The paleo-fluid deposits that were subjected to the alteration of the deposit have made the genesis of the deposit deeper
