Abstract
An integrated geological-geochemical-geophysical approach is presented for the thermal modeling of a magma chamber in order to predict the temperature field distribution in two geothermal fields (Los Humeros, Puebla and Los Azufres, located in the Mexican Volcanic Belt (MVB). For both geothermal systems, it is shown that the temperature field simulated from cooling of a shallow 5 km depth) magma chamber for the entire volcanic history of the caldera and taking into account the thermal effects of geological processes, such as fractional crystallization (FC), magma recharge (MR) and high convection (HC) in the geothermal reservoir, is in general agreement with the temperatures actually measured in wells.
