Peculiarities of present-day sulfide mineralization at 19°15′—20°08′ N, Mid-Atlantic Ridge

Abstract

Based on studies conducted on the 33rd cruise of the R/V Professor Logachev in 2010, a new type of sulfide mineralization of the mid-oceanic ridges has been established. It was formed in the present-day organic sediments due to diffuse penetration of hydrothermal fluids that emanated along the fractures in basalts on the slopes of the Mid-Atlantic Ridge.
