Chemical Equilibrium in Hydrothermal Systems: The Case of Los Azufres Geothermal Field, Mexico
International Geology Review, 2002This work presents a review of the geological, hydrogeochemical, and mineralogical information related to the Los Azufres geothermal field, along with new isotopic data from hydrothermal calcite and quartz. The equilibrium state between present-day geothermal fluids and hydrothermal mineral phases in this field was examined using mineralogical ...

Abstract We explored applications (including limitations) of Gauss's theorem to the study of silicic calderas. First it enables us to determine the mass deficiency from calderas. Mass deficiency itself has also other potential applications. It enables to make qualitative comparisons between calderas. We can use the mass deficiency to test, in a quick

LOS AZUFRES GEOTHERMAL FIELD AS A PROTOTYPE OF MDL ON THE ELECTRICAL SECTOR
INCEPTUM, 2022La geotérmica es una forma limpia de producción eléctrica, sin embargo, dentro de su proceso, genera emisiones importantes de gases de efecto invernadero (gei). En México, el campo geotérmico Los Azufres produce anualmente 14 millones de toneladas (torres, 2007), de vapor endógeno, de los cuales 3% (420.000 tco2) aproximadamente son rechazadas a la ...

Well Testing At Los Azufres Geothermal Field
SPE Annual Technical Conference and Exhibition, 1979Abstract It is important to determine reservoir characteristics as early in the life of the reservoir as possible. This paper presents a summary of the efforts made by Comision Federal de Electricidad to evaluate Los Azufres field by means of the implementation of standard pressure transient analysis techniques to ...

The Los Azufres, Michoacan, Mexico, geothermal field
Journal of Hydrology, 1982Abstract Fifteen deep exploratory and production wells in a 30-km2 area have permitted the study of both the primary igneous petrology and the secondary geothermal system and its associated mineralization. The Los Azufres field lies on a complex Plio-Pleistocene succession of basalts, andesites, dacites and rhyolites, each with its associated tuffs ...

Volcanic stratigraphy of the Los Azufres geothermal area, Mexico
Journal of Volcanology and Geothermal Research, 1985Abstract The Los Azufres volcanic center, located 200 km northwest of Mexico City, is one of a number of Pleistocene silicic volcanic centers with active geothermal systems that lie north of the axis of the Mexican Neovolcanic Belt. Silicic volcanism began approximately 1 m.y. ago with eruption of the Agua Fria rhyodacite to high-silica rhyolite lava

Estudio y caracterización de roca mineral de los azufres
Revista Tendencias en Docencia e Investigación en Química, 2022This work presents a study and characterization of a mineral rock in Ciudad Hidalgo, Michoacán, Mexico. The grain size of 48 μm was chosen for the characterization of the material. By X-Ray Diffraction, the mineralogical phases of the Alunite KAl₃(SO⁴)₂(OH)₆, Cristobalite SiO₂, and Kaolinite Al₂Si₂O₅ were determined.

A chlorite solid solution geothermometer the Los Azufres (Mexico) geothermal system
Contributions to Mineralogy and Petrology, 1985Chlorite constitutes a major hydrothermal alteration product of metamorphism of andesites, in the active geothermal system of Los Azufres (Mexico). Electron microprobe analyses performed on a set of crystals from each sample show wide variations in composition. Correlation coefficients among chemical constituents were calculated.

Elemental analysis of the geothermic microecology of the Los Azufres (Mexico) volcanic complex
Journal of Radioanalytical and Nuclear Chemistry, 2019Three geothermal microecologies, constituted of fumaroles, hydrothermal springs and the native volcanic superstratum at the Los Azufres (Mexico) volcanic complex, have been analysed for the concentrations of Cd, Hg, Pb, Th and U in the tissues and rhizospheric soils of the extremophilic plants that colonise the fumaroles, as well as in the sediments ...
