Thermodynamic Models of Submarine Hydrothermal Systems

摘要

This contribution presents a method for constructing thermodynamic models of convective hydro-thermal systems with an exogenous source of solutions.With the example of a simulation of modern hydrother-mal systems on the ocean floor,the prospects of such a method for the interpretation and forecasting of hydro-thermal mineralization are discussed.A procedure for constructing isotopic chemical models is described using sulfur isotopes as an example.The role of boiling within oceanic hydrothermal systems in the formation of metalliferous deposits is evaluated. This paper is intended for geologists who specialize in hydrothermal ore deposits,geochemists,and marine geologists and can be used by students as a guide for the simulation of ore-forming processes.
