Abstract:

During the last 25-30 ka a layer of pelagic sediments covering basement rocks was formed within the hydrothermal field located at 14°45'N (Logachev hydrothermal field). Composition of edaphogenic minerals from bottom sediments points to the fact that serpentinites or serpentinous abyssal rocks and gabbroids prevail among rock outcroppings within the hydrothermal field. Hydrothermal activity of the studied area extends over at least 25-30 ky. A sharp increase in hydrothermal activity took place at the boundary between Würm and Holocene. Intensive discharge of ore-bearing fluids persists up to present time.
