Smectite, illite, celadonite and chlorite are the major products of alteration of rhyolites and andesites, in the upper part of the Los Azufres geothermal system. Changes in mineral assemblages and composition of phases are observed as a function of depth and host rock lithology. Two different sequences characterize the rhyolites and the andesites from

The Los Azufres geothermal complex of central Mexico is characterized by fumaroles and boiling hot-springs. The fumaroles form habitats for extremophilic mosses and ferns. Physico-chemical measurements of two relatively pristine fumarolic microcosms point to their resemblance with the paleo-environment of earth during the Ordovician and Devonian ...

Geochemistry of boron in fluids of Los Humeros and Los Azufres hydrothermal systems, Mexico.
2010Separated water from geothermal wells of high-temperature geothermal fields Los Humeros and Los Azufres in Mexico are unusually rich in boron. According to the isotopic composition, boron in both fields has magmatic origin. Since the Los Humeros fluids, in contrast to Los Azufres, do not show any correlation between B and Cl and have Cl/B ?

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, 2005Abstract 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

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 ...

Late Pleistocene rhyolitic explosive volcanism at Los Azufres Volcanic Field, central Mexico
2012Abstract Los Azufres Volcanic Field hosts the second most important geothermal field of Mexico, with a production of 188 MW of electricity. Based on fieldwork and new geochronological data (14C and 40Ar/39Ar) we define that activity at Los Azufres Volcanic Field started some 1.5 Ma with the emission of basaltic to rhyolitic lavas, and ...
