Eruptive chronology of the Acoculco caldera complex – A resurgent caldera in the eastern Trans-Mexican Volcanic Belt (México)
(Elsevier, 2020)The Acoculco caldera complex (ACC) is located in the eastern part of the Trans-Mexican Volcanic Belt in the northern part of the State of Puebla. The complex sits at the intersection of two regional fault systems with NE- ... -
Tectonic and magmatic controls on the evolution of post-collapse volcanism. Insights from the Acoculco Caldera Complex, Puebla, México
The Acoculco Caldera Complex (ACC; 2.7–0.06 Ma) is located in the eastern part of the Trans Mexican Volcanic Belt, México. The ACC produced three major explosive eruptions: the Acoculco andesitic ignimbrite (AI; 2.7 Ma; ... -
Estimation of Fracture Energy from Hydraulic Fracture Tests on Mortar and Rocks at Geothermal Reservoir Temperatures
(Springer Nature, 2021-05-17)An Enhanced Geothermal System (EGS) can be thought of as an underground heat exchanger designed to extract geothermal energy. The performance of these systems can be improved by increasing permeability with hydraulic ... -
Invariant TE and TM impedances in the marine magnetotelluric method
( The Royal Astronomical Society, 2020)The magnetotelluric (MT) impedance tensor has a nil diagonal when one of the axes of the coordinate system coincides with the strike of a 2-D structure. In general, real data are full tensors either because of 3-D effects ... -
Genesis of magmas from the Tres Vírgenes Volcanic Complex, Baja California Sur, Mexico
(2019)The late Pleistocene Tres Vírgenes Volcanic Complex (TVVC), Baja California Sur, Mexico, is formed by 3 volcanic edifices: El Viejo, El Azufre and La Vírgen. Although the TVVC is emplaced in a tectonic environment where ... -
Microstructural characterization and mechanical response of Inconel 600 welded joint
(Elsevier, 2019)In this study, plates of IN600 super alloy were gas metal arc welded with an ERNiCrMo-3 filler wire and the effect of the welding process was evaluated in the as-welded joint in terms of microstructure, mechanical properties ... -
Structure of the Cerro Prieto Pull-apart basin from joint inversion of gravity, magnetic and magnetotelluric data
(Elsevier, 2019)The large transform fault system that separates the Pacific and the North American plates in the Gulf of California is conformed by a system of oblique rifts and large dextral transform faults. Besides their seismogenic ... -
Geologic Map of Los Humeros volcanic complex and geothermal field, eastern Trans-Mexican Volcanic Belt
(UNAM, 2018)Esta es una versión actualizada del mapa geológico del Complejo Volcánico Los Humeros (CVLH) y campo geotérmico, basada en una caracterización actualizada de las unidades litológicas y contactos, características estructurales, ... -
Hybrid Solar-Geothermal Energy Absorption Air-Conditioning System Operating with NaOH-H2O—Las Tres Vírgenes (Baja California Sur), “La Reforma” Case
(MDPI, 2018)Solar and geothermal energies are considered cleaner and more useful energy sources that can be used to avoid the negative environmental impacts caused by burning fossil fuels. Several works have reported air-conditioning ... -
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 ... -
Robust estimation of temporal resistivity variations: Changes from the 2010 Mexicali, Mw 7.2 earthquake and first results of continuous monitoring
(Society of Exploration Geophysicists, 2018)The magnetotelluric (MT) method is a well-known geophysical technique in tectonic and reservoir exploration studies. In recent years, several works have proven that the MT method is a valuable tool for monitoring fluid ... -
Splitting marine controlled-source electromagnetic responses into sea and subseafloor contributions: Grounding the air wave
(Society of Exploration Geophysicists, 2017)We have found how the effects of the air wave in marine controlled-source electromagnetic (CSEM) methods gradually vanish in the sea for shallow waters, and how at the same time they gradually grow below the seafloor, in ... -
Stable 2D magnetotelluric strikes and impedances via the phase tensor and the quadratic equation
(Society of Exploration Geophysicists, 2017)A combination of the magnetotelluric phase tensor and the quadratic algorithm provides a fast and simple solution to the problem of a 2D impedance tensor distorted by 3D electrogalvanic effects. The strike direction is ... -
A rock magnetic fingerprint of hydrothermal alteration in volcanic rocks - An example from the Los Azufres Geothermal Field, Mexico
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; ... -
Heavy metal sources and anthropogenic enrichment in the environment around the Cerro Prieto Geothermal Field, Mexico
The Cerro Prieto Geothermal Field (CPGF) is the biggest in Mexico, fourth worldwide, and it started electricity generation in 1973. This work correlates heavy metals in environmental samples, tracing the geothermal energy ... -
Systematic heat flow measurements across the Wagner Basin, northern Gulf of California
A primary control on the geodynamics of rifting is the thermal regime. To better understand the geodynamics of rifting in the northern Gulf of California we systematically measured heat-flow across the Wagner Basin, a ... -
Joint two-dimensional inversion of magnetotelluric and gravity data using correspondence maps
An accurate characterization of subsurface targets relies on the interpretation of multiple geophysical properties and their relationships. There are mainly two links to jointly invert different geophysical parameters: ... -
Geology of La Reforma caldera complex, Baja California, Mexico
(Taylor & Francis, 2019)A new geological map at 1:50,000 scale of La Reforma Caldera Complex has been produced applying modern survey methodologies to volcanic areas. This map aims to represent a reliable and objective tool to understand the ... -
Geophysical modeling of La Primavera caldera and its relation to volcanology activity based on 3D susceptibility inversion and potential data analysis.
(Elsevier, 2019)La Primavera (LP) is a rhyolitic caldera located in the western sector of the Trans-Mexican Volcanic Belt (TMVB). LP is located close to the triple point junction of the Chapala, Colima and Tepic-Zacoalco rifts. To understand ... -
Geology of the late Pleistocene Tres Vírgenes Volcanic Complex, Baja California Sur (México)
(Taylor & Francis, 2019)The geological map of the Tres Vírgenes Volcanic Complex (TVVC) Baja California Sur, México consists of three northeast-southwest aligned stratovolcanoes named from older to younger, El Viejo, El Azufre, and La Virgen. The ...
