除某些表生铀矿床,如砂岩中的钙结岩型和卷型,在多种类型铀矿的岩石中发现并研究了流体包体,铀矿的形成温度近400℃,但多数是在90—250℃的中温下形成的。仅通过少数几个研究就足以说明,成矿作用的深度比以前认识的要大。流体的化学成分可以从几乎是纯水到很浓的卤水,CO_2~-也是一种常见组分。在某种情况下,进行气体分析可以确定流体的fo_2以及铀迁移和沉淀的一些重要参数。 In addition to some superficial uranium deposits, such as calcareous and volcanic types in sandstone, fluid inclusions have been discovered and studied in rocks of various types of uranium deposits, forming uranium at temperatures near 400 ° C, but mostly at 90-250 ° C under the temperature formed. Only a few studies are enough to show that the depth of mineralization is greater than previously known. Chemical composition of the fluid can be almost pure water to a very strong brine, CO_2 ~ - is also a common component. In some cases, performing a gas analysis can determine fo_2 as well as some important parameters of uranium migration and precipitation.
