Abstract—

This paper considers examples of “hydrogenic” commercial uranium deposits termed as “sandstone-hosted” in the English literature and characterized by so-called “reduced-type alterations.” In addition to the case when they are absent at the deposit, a few characteristic alterations are identified in different ratios, such as rock bleaching, iron redistribution, argillization, carbonatization, bituminization, sulfidization, and other changes in the host rocks. The nature of these alterations varies in different areas, and their composition depends mainly on the groundwater composition and formation conditions in the studied region. Alterations related to waters of oil and gas basins, as well as to deep carbonic basement waters, are the most pronounced. The alterations are less significant at deposits related to “nitric spring” discharge.

外源性渗透铀矿床的还原型蚀变及其与地下水上升的关系

摘要-

本文考虑了在英国文学中被称为“砂岩气藏”且具有所谓“还原型蚀变”特征的“水合”商业铀矿床的实例。除了在矿床中不存在的情况以外，还发现了一些不同比率的特征性变化，例如岩石漂白，铁的重新分布，固氮化，碳化，沥青化，硫化和其他主岩体变化。这些变化的性质在不同地区有所不同，其组成主要取决于研究区域的地下水组成和形成条件。与油气盆地的水以及深层的碳基底水有关的变化最为明显。在与“硝酸盐弹簧”排放有关的沉积物上，变化不那么明显。
