Living organisms pseudomorphs in modern volcanites of the Mid-Atlantic Ridge

Autor: I. G. Dobretsova

Publikováno v: Vestnik of Geosciences. 12:26-31

The study of samples of volcanic rocks, sulfide ores, and near-ore metasomatites from the bottom of the Atlantic Ocean resulted in the discovery of vital forms of organisms: foraminiferal shells, mineral pseudomorphs after the bodies of polychaetes,

Hydrothermal manganese mineralization in the Peterbourgskoye ore field (North Atlantic)

Autor: I. G. Dobretsova, G. N. Baturin, V. T. Dubinchuk

Publikováno v: Oceanology. 54:222-230

The manganese crust covered by pelagic sediment was recovered from the 3 km depth from the Peterbourgskoye ore field located on the eastern flank of the Mid-Atlantic Ridge. The crust comprises a platy brittle aggregate 1–5 cm thick made of black he
