Element mobility during the hydrothermal alteration of rhyolitic rocks of the Los Azufres geothermal field, Mexico

Geothermics, 2008
Abstract 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 compositions of altered drill cuttings (taken above 450 m depth) with those of fresh rock outcrop samples.

Variability in the gas phase composition of fluids discharged from Los Azufres geothermal field, Mexico

Journal of Volcanology and Geothermal Research, 1991
Abstract 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 of fluids discharged by a number of deep wells in continuous production.

A rock magnetic fingerprint of hydrothermal alteration in volcanic rocks - An example from the Los Azufres Geothermal Field, Mexico

Journal of South American Earth Sciences, 2019
Abstract Drill rock cuttings from different depths of two geothermal wells (Az-26 and Az-49) from the Los Azufres Geothermal Field (LAGF), Mexico, were analyzed for rock magnetic properties (magnetic susceptibility, χlf; frequency-dependent susceptibility, χfd; susceptibility of anhysteretic remanent magnetization, χARM; isothermal remanent ...

LOS AZUFRES GEOTHERMAL FIELD AS A PROTOTYPE OF MDL ON THE ELECTRICAL SECTOR

INCEPTUM, 2022
La 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, 1979
Abstract 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, 1982
Abstract 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 ...

Environmental Impact by Spill of Geothermal Fluids at the Geothermal Field of Los Azufres, Michoacán, Mexico

Water, Air, and Soil Pollution, 2000
Monitoring of surface water and shallow aquifers inside and outside of the Los Azufres geothermal fieldduring the period November 1994 to May 1996 led to thedetection of some contamination of surface water andshallow aquifers due to exploitation of the deepbrines.

Hydro-geochemical and isotopic fluid evolution of the Los Azufres geothermal field, Central Mexico

Applied Geochemistry, 2005
Abstract Hydrothermal alteration at Los Azufres geothermal field is mostly propylitic with a progressive dehydration with depth and temperature increase. Argillic and advanced argillic zones overlie the propylitic zone owing to the activity of gases in the system. The deepest fluid inclusions (proto-fluid) are liquid-rich with low salinity, with NaCl

The origin of reservoir fluids in the geothermal field of Los Azufres, Mexico — isotopical and hydrological indications

Applied Geochemistry, 2001
Abstract The calculation of hydrological balance resulted in a potential, average annual infiltration rate of 446±206 mm/m 2 for the Los Azufres geothermal area, which corresponds to a total of 82×10 6 m 3 per a. Due to the highly fractured and faulted structure of the volcanic formations, a considerable potential for the infiltration of recent ...

Microbial diversity in Los Azufres geothermal field (Michoacán, Mexico) and isolation of representative sulfate and sulfur reducers

Extremophiles, 2014
Los Azufres spa consists of a hydrothermal spring system in the Mexican Volcanic Axis. Five samples (two microbial mats, two mud pools and one cenote water), characterized by high acidity (pH between 1 and 3) and temperatures varying from 27 to 87 °C, were investigated for their microbial diversity by Terminal-Restriction Fragment Length Polymorphism ...
