许多微生物,和它们的活动在岩石中和水中与分散的重金属相互作用。使它们活化,堆积和沉积在当代及古老的环境中。微生物可以影响金属矿床的形成,从早元古(24亿年)开始,虽然它们也发现在更老的时期(可能从38亿年),细菌的新陈代谢促进了一系列重要的成矿作用,首先是铁、锰、砷,锑、硫和其它元素的氧化作用。类似的作用常常发生在厌氧的情况下,形成层状的铁矿,金属物质的矿源是在前寒武纪海洋中大量呈 Many microorganisms, and their activities, interact with dispersed heavy metals in rock and water. Make them activate, pile up and deposit in the contemporary and ancient environment. Microbes can influence the formation of metallogenic deposits. Since the Early Proterozoic (2.4 billion years), although they also found that at older ages (possibly from 3.8 billion years) bacterial metabolism promoted a series of important metallogenic processes, firstly Iron, manganese, arsenic, antimony, sulfur and other elements of the oxidation. A similar effect often occurs in anaerobic conditions, the formation of layered iron ore, metal resources in the Precambrian ocean was a large number of
