UDC (553.252.2:550.72):549 PECULARITIES OF MINEROGENESIS IN THE MICROBIAL COMMUNITIES
This paper discusses pecularities, which can help to identify or assume a microbial activity in geological deposits. The features are determined on the ground of minerals study. These minerals were formed in modern microbial communities. Such characteristics include skeletal remains; prints of microorganism cells and filaments inside minerals, pseudomorphs of enveloping (covers) on cells and filaments; mineral deposition due to changes in the oxidation degree of elements and formation of specific Eh-pH conditions that are not common for an environment; mineral deposition as a result of elements concentration by microorganisms.
Key words: minerals, cyanobacterial mats, thermal springs.
