微生物在十红滩铀成矿过程中的作用

Effect of Microorganism on Mineralization of Interlayer Oxidation Zone Sandstone Type Uranium Deposit in Shihongtan

微生物在矿床的形成中直接或间接参与了成矿过程,某些细菌从U6+还原成U4+过程中获得生存能量,在铀矿化的形成过程中发挥了重要作用。通过对十红滩铀矿床容矿层岩石的不同地球化学分带中细菌的分布特征研究,分析和探讨了不同细菌的生命代谢特征与铀迁移、富集成矿的关系,建立十红滩地区铀矿微生物的成矿机制。

Microorganism play a direct and undirect role in the process of deposit formation.Some cells can obtain the existing energy during the process from U6＋ to U4＋ and play a very important role in the process of uranium minerlization.This paper analysed the distribution character of cells in different geoG chemistry zone of Shihongtan uranium deposit and discussed the relationship between the metabolism of cell life and the migration and enrichment of uranium.The paper established the mineralizing model in Shihongtan uranium deposit.
