摘要：

It is shown that peat bogs, which accumulate coal- and siderite-bearing sediments, serve as a generator of ferruginous solutions with the significant part of Fe migrating from them in the form of metalloorganic compounds. The stability of organic Fe-bearing complexes provides favorable conditions for the late diagenetic - catagenetic siderite formation in adjacent sea basins. It has been established that the formation of Phanerozoic coals, oil shales, and black shales was nearly coeval with the formation of goethite - chlorite - siderite ores. The paper discusses the influence of volcanic activity on the formation of Precambrian - Phanerozoic iron ore deposits and emphasizes the significance of siderite formation in the general evolution of the sedimentary iron ore formation.
