Abstract
The condensation of CO2 and steam in groundwaters above zones of boiling is thought to produce the CO2 enriched fluids that are commonly found on the margins of high-temperature geothermal systems. Evidence for significant CO2 flux has been found in fluid inclusions fhm the geothermal systems at Los Azufies, Mexico, and 2imif.Guatemaia. These geothermal fieIds have measured temperares close to 300 C. CO2 rich fluid inclusions are widely distributed in both geothermal systems. These inclusians define a cap over each system that thickens outward from the main upwelling zone.
