The Petrology of Volcanic-Edaphogenic Coarse Clastic Material from the Wima Transform Fault, Central Atlantic

The volcanic–edaphogenic material raised by a grab sampler in the 53th voyage of R/V Akademik Ioffe from the depth of 4685 m in the area of the Wima transform fault was studied. The mineralogy and the distribution of chemical elements between the minerals of igneous origin are considered. Initial approximate modeling of some conditions of the formation of this material was performed. The hydrogenous nature of ferromanganese crusts found in fragments of igneous formations was suggested. The relationship between the formation of volcanic–edaphogenic material and the activity of near-bottom oceanic currents was analyzed.
