Paper Abstract

Hundreds of specimens of phosphorites, bauxites and manganese ores of different genetic types from all continents, from Quarternary to Proterozoic by age were studied with SEM analysis. Mineralized remains of prokaryotes and to less degree of eukaryotes made up the majority of such unchanged ores. The process of replication of biological fabric with different ore matters is general and determining for the origin of these ores, though for bauxites is characteristic somewhat pure chemical deposition during initial transformation stage of host rocks. Highly productively during initial stages of the ore genesis favors for phosphate and manganese ores, beside some other factors. The microbiota actively take part in decomposition of rocks during bauxite genesis side by side with forming of ore biomorphoses.
