据报道,苏联最近通过一个白垩纪含碳磨砾层中的矿床实例,对伴随后生成矿过程中有机质的变化进行了研究。采用物理和化学的综合分析方法研究了作为主要矿化剂的有机质的特性。铀富集和有机质的氧化程度之间明显的关系对于矿石定位是最为特征的,但是矿石中铀含量和有机质的含量相互间没有直接关系。在氧化带底部氧化过程中,含铀的酸性水渗透到灰色层中形成铀矿化的聚集,与其它沉积岩相比褐煤物质具有最大的吸附力,是铀的沉淀剂。由于有机质的氧化、铀发生还原,而铀矿物本身(铀石、沥青铀矿)的形成伴有吸附作用。因而,后生氧化是铀在有机质
According to reports, the Soviet Union recently through a Cretaceous carbonaceous gravel deposit in the case of organic matter in the process of accompanying post-formation changes were studied. The physical and chemical comprehensive analysis methods were used to study the characteristics of organic matter as the main mineralizer. The obvious relationship between uranium enrichment and the degree of oxidation of organic matter is most characteristic of ore location, but the uranium content and organic matter content of ore are not directly related to each other. During oxidation at the bottom of the oxidation zone, uranium-bearing acidic water permeates into the gray layer to form uranium mineralized aggregates. Compared with other sedimentary rocks, lignite has the largest adsorption capacity and is a precipitating agent of uranium. Due to the oxidation of organic matter, uranium is reduced and uranium itself (uraninite, uraninite) is adsorbed. Thus, epigenetic oxidation is uranium in organic matter
