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

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, deposit feeders, and other fauna. This allows us to understand not only modern geological processes in the depths of the oceans, but also to reconstruct events of the distant geological past based on the principle of actualism.
