1. Introduction. To understand the main and rare element content of sedimentary ore formations like iron and manganese ores, it is important to consider the role of microbial life (in particular bacteria and fungi) in the geological context of mineralization and mobilization processes, because the mechanisms governing such activities often supersede purely inorganic reactions.
