| 摘 要： | 通过对东胜砂岩型铀矿床中岩石样品的生物学分析,发现铀矿各区域分布着不同种属的硫酸盐还原菌(SRB),其分布规律和矿床环境因素密切相关;通过对地下水中铀的还原实验和SRB—水—岩模拟实验,研究了SRB的生长、繁殖、代谢和铀矿形成之间的相互作用,认为SRB通过产生还原作用形成有利于自身生存的微生态环境,改变了铀的价态和溶解...

| Abstract: | A biological analysis of rock samples in Dongsheng sandstone-type uranium deposits found that different species of sulfate-reducing bacteria （SRB） occurred in various regions of the uranium deposit. Their distributions are closely related to the environmental factors of the deposit. The interactions of growth， reproduction and metabolism of SRB and uranium ore formation was studied by carrying out reduction experiments of uranium in groundwater and simulated SRB-water-rock mineralization. These showed that SRB formed a micro-ecological reducing environment beneficial to its survival， which altered the valence and solubility of the uranium and directly led to the formation of the Dongsheng sandstone-type uranium deposit. |
