Research of ore elements migration forms in the hydrothermal solutions of the Mid-Atlantic ridge

Abstract

On the basis of geological and hydrogeochemical analysis, the issue of forming of hydrothermal plumes in Atlantic Ocean is considered. Forms of the ore elements migration in hydrothermal solutions of the Logachev vent field (14°45' N) were researched. According to thermodynamic calculations the main migration forms of zinc and copper were determined in the vent orifice, buoyant and lateral hydrothermal plumes. This analyses allowed establishing the main features of migration forms alteration. In the short term knowledge of migration forms correlation will give a possibility to improve solution analysis with ion-selective electrodes, which are used in hydrothermal plumes prospecting in the ocean, and also to improve a methodology of geochemical research data interpretation and, as the result, to increase a prospecting efficiency.
