摘要：
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.
