Abstract—The geological environment of ore formation in sandstone-type uranium deposits is considered in light of modern geomicrobiological and ecological (environmental) mineralogical data related to solving environmental bioremediation problems (purification of the near-surface environment via bacterial fixation of radionuclides). Analysis of the literature data shows the possible ore-forming role of the biogenic factor in the formation of infiltration sandstone-type uranium deposits, which is considered here with an example of their paleochannel subtype with widespread phosphate black uranium ores. The bacterial factor is proposed as one of the main mechanisms for the occurrence and movement of the redox front during hypergene processes in ore-bearing sedimentary sandstone strata.

摘要——根据解决环境生物修复问题（通过放射性核素的细菌固定净化近地表环境）的现代地球微生物学和生态（环境）矿物学数据，考虑了砂岩型铀矿床成矿的地质环境。文献资料分析表明，生物成因在渗透砂岩型铀矿床形成过程中可能起成矿作用，这里以分布广泛的磷酸盐黑铀矿的古河道亚型为例加以考虑。细菌因素被认为是含矿沉积砂岩地层表生过程中氧化还原前沿发生和运动的主要机制之一。
