Combining ammonium mapping and short-wave infrared (SWIR) reflectance spectroscopy to constrain a model of hydrothermal alteration for the Acoculco geothermal zone, Eastern Mexico.
The Acoculco geothermal system is hosted by a caldera complex located at the eastern portion of the Trans-Mexican Volcanic Belt. Surface manifestations are scarce and consist of low temperature, bubbling, acid–sulfate ... -
Comparison of the energetic performance of a binary cycle and a flash evaporation binary cycle using low enthalpy geothermal energy
(Taylor and Francis Online, 2016)In this article, the comparison of the energetic performance of a binary cycle and a modified binary cycle with flash evaporation is presented, both using a low-enthalpy geothermal resource. The comparative analysis is ... -
Distribución de anomalías geotérmicas en México: Una guía útil en la prospección geotérmica
Desde hace unos 45 años, México figura como pionero y líder en el continente Americano en la explotación de recursos geotérmicos para la generación comercial de electricidad. De los 24 países en el mundo que en 2015 utilizan ... -
Effect of heat input and accumulated fatigue damage on mechanical properties of dissimilar AL-6XN/316L welded joints
In this study, plates of AL-6XN and 316L stainless steels were gas metal arc welded with an ER-NiCrMo3 filler wire and the effect of two different heat inputs and different accumulated fatigue damage is evaluated in terms ... -
Effects of reclaimed water discharge in the Maneadero coastal aquifer, Baja California, Mexico
(Elservier, 2018)Since 2014, reclaimed water has been used for agricultural irrigation and it has been discharged on a riverbed of the Maneadero aquifer, Baja California, Mexico. To determine the effects of reclaimed water on groundwater ... -
Enriched Galerkin finite element approximation for elastic wave propagation in fractured media
(Elsevier, 2018)Finite Element Methods (FEM) are becoming increasingly popular in modeling seismic wave propagation. These methods provide higher order accuracy, geometrical flexibility and adaptive gridding capabilities that are not easy ... -
Eruptive chronology and tectonic context of the late Pleistocene Tres Vírgenes volcanic complex, Baja California Sur (México)
(Elservier, 2018)Based on a detailed geological map and stratigraphy aided by new 230Th/238U and 206P/238U age determinations we established the eruptive chronology of the Tres Vírgenes Volcanic Complex (TVVC). The complex consists of three ... -
Evaluation of the solute geothermometry of thermal springs and drilled wells of La Primavera (Cerritos Colorados) geothermal field, Mexico: A geochemometrics approach
A detailed study on the solute geothermometry of thermal water (18 springs and 8 drilled wells) of La Primavera geothermal field (LPGF) in Mexico has been carried out by employing a geochemical database compiled from the ... -
Evidence of a shallow magma reservoir below Los Humeros volcanic complex: Insights from the geochemistry of silicate melt inclusions
(Elservier, 2018)Los Humeros volcanic complex (Eastern Trans Mexican Volcanic belt) is one of the three most important geothermal fields in Mexico and is currently producing electricity (ca. 90 MW). It is therefore pertinent to constrain ... -
