Abstract

Features of submarine hydrothermal discharge and geochemical anomalies in bottom waters of Mid-Atlantic Ridge are observed. In the typical section of hydrothermal halos two major zones could be distinguished: forming by the rising stream gravitationally non-stable structures and more stable formations on the horizon of lateral flow. Discrete structure of hydrothermal plumes and matter differentiation are discussed. Different types of fluid discharge are revealed on the Logatchev field. As a result three kinds of hydrothermal plumes are forming: of positive, neutral and negative buoyancy.
