Three dimensional temperature simulation from cooling of two magma chambers in the Las Tres Vírgenes geothermal field, Baja California Sur, Mexico
A three-dimensional (3D) numerical model is proposed for natural state simulation of the Las Tres Vírgenes (LTV) geothermal system from emplacement and cooling of the heat source. A conceptual model of the LTV volcanic ...
Fluid chemistry and temperatures prior to exploitation at the Las Tres Vírgenes geothermal field, Mexico
Generation of electricity at the Las Tres Vírgenes (LTV) geothermal field, Mexico, began in 2001. There are currently nine geothermal wells in the field, which has an installed electricity generating capacity of 10 MWe. ...
Geochemistry of Los Humeros Caldera, Puebla, Mexico
Geochemistry of Pliocene to recent volcanic rocks from Los Humeros caldera (19°30′ N - 19°50′ N and 97°15° W - 97°35′ W) in East-Central mexico is described. The volcanic rocks from this area seem to represent both alkali ...
Temperature field simulation with stratification model of magma chamber under los humeros caldera, Puebla, Mexico
A simulation of the temperature field underlying Los Humeros caldera is obtained through numerical solution of the energy-conservation equation for a conductive heat flow process. The up-date information on geological, ...
On the magma chamber characteristics as inferred from surface geology and geochemistry: examples from Mexican geothermal areas
A procedure is described which enables us to obtain estimates of some physical and chemical characteristics of sub-surface magma chambers. This is applied to three geothermal areas of the Mexican Volcanic Belt (MVB) in ...
Heat liberation by fractional crystallization in two geothermal fields in the Mexican Volcanic Belt [Aporte de calor por cristalizacion fraccionade en dos campos geotermicos del Cinturon Volcanico Mexicano]
A methodology for the computation of heat liberated by fractional crystallization in a magma chamber is presented, with application to Los Azufres and Los Humeros geothermal fields. The heat from fractional crystallization ...
SolGeo: A new computer program for solute geothermometers and its application to Mexican geothermal fields
The freely available computer program Solute Geothermometers (SolGeo) was written and tested using geochemical data and reported geothermometric temperatures from several geothermal wells from around the world. Subsurface ...
Element mobility during the hydrothermal alteration of rhyolitic rocks of the Los Azufres geothermal field, Mexico
The effects of hydrothermal alteration on major, rare-earth, and other trace-element concentrations in rhyolitic rocks of the Los Azufres geothermal field, Mexico, were investigated by statistically comparing the chemical ...
X-ray diffraction analysis of hydrothermal minerals from the Los Azufres Geothermal System, Mexico
Los Azufres is an active geothermal field located in the middle of the Mexican Volcanic Belt (MVB), a vast Miocene-Recent, E-W-oriented volcanic province spanning central Mexico. Three wells - Az-5, Az-28, and Az-31 - from. ...
Variability in the gas phase composition of fluids discharged from Los Azufres geothermal field, Mexico
Studies related to hydrological structure of the Los Azufres geothermal field and its effects on the exploitation of the field for generation of electrical energy have included a program of sampling and chemical analysis ...
