Paper Abstract

Owing to the latest investigations in bacterial paleontology and geomicrobiology a number of minerals known to be formed with the participation of micro-organisms increases continuously. 12 - 15 years ago we know nearly 20 minerals: carbonates (calcite, aragonite, monohydrocalcite), phosphates (dalite, francolite, struvite, vivianite, and some other), sulfates (jarosite), ferric oxides (magnetite, ferrohydrite), sulfides (pyrite, hydrotroilite, sphalerite, wurtzite, and some others) (Lowernstan, Weiner, 1989). Now their number is several times greater. Quartz cristobalite, pyrolusite, silicates (including layer ones), and feldspars are of special interest (Geomicrobiology..., 1997; Tazaki et al., 1997; Geptner et al., 1997; Bacterial paleontology, 2002).
