Abstract

Volcano-edaphogenic material was studied, which was raised by a grab sampler during cruise 53 of the R/V Akademik Ioffe from the water depth of 4685 m in the area of the Vima transform fault. Mineralogy and the distribution of chemical elements between the minerals of magmatic origin are considered. An attempt was made to roughly estimate the crystallization temperature of aphyric basalts. The hydrogenic nature of ferromanganese crusts covering the fragments of magmatic origin is has been clarified. The relationship between the formation of volcano-edaphogenic material and bottom ocean currents is analyzed.
