Analytical Modeling At Valles Caldera - Redondo Geothermal Area (White, 1986)
ExpActivityDateEnd 1986  +

Notes Results indicate the presence of a normal
Results indicate the presence of a normal enthalpy, lower-chloride fluid and an excess enthalpy, higher-chloride fluid enriched in deuterium and 18O. These distinct chemical properties can be explained by adiabatic cooling or boiling of fluids at 170°C during upward convection along the central fault system in the reservoir, followed by conductive reheating during downward movement. Computer-based chemical modeling using the EQ3NR code indicates stability with the quartz-albite-K mica-epidote-chlorite-calcite-anhydrite-pyrite mineral assemblage, which is in agreement with observed minerals in well cuttings. Together, these results imply a constant temperature range of 260-320°C during evolution of the Redondo reservoir.
