Evolution of Liquid-Dominated Hydrothermal Systems with with Parasitic Vapor-Dominated Zones

Abstract

Liquid-dominated hydrothermal systems with parasitic vapor-dominated zones occur in regions of moderate great topographic relief where steam and liquid phases separate, with steam rising through a vapor-dominated zone toward areas of steam and stew- heated discharge at relatively high elevations and liquid flowing laterally toward areas of high- chloride .spring discharge at relative l y low elevations. simulations of the evolution such systems demonstrate the mechanisms responsible for their de ment, and quantify the factors Coling the corresponding temperature and pressure distributions and the rates of upflow of steam and lateral flow of Iiquid.
