2 ¾ dimension modeling of the aeromagnetic anomaly of Volcán de Colima, western Mexico
(2012)"Se presentan los resultados de un modelo 2 ¾ D de la anomalía aeromagnética del Volcán de Colima ubicado en la porción sur del Complejo Volcánico de Colima. El modelo estructural documenta la presencia de una cámara ... -
A new computer program TecDIA for multidimensional tectonic discrimination of intermediate and acid magmas and its application to the Bohemian Massif, Czech Republic
(Czech Geological Society, 2015)"A new computer program TecDIA written in Java, for the application of 35 previously-defined multidimensional diagrams for the tectonomagmatic discrimination of intermediate and acid magmas is briefly described. A detailed ... -
Bottom topography, recent sedimentation and water volume of the Cerro Prieto Dam, NE Mexico
(2014)"The Cerro Prieto dam, a relatively small water reservoir in NE Mexico, is one of the main resources of potable water for Monterrey, a city with a population of about four million inhabitants. A high resolution seismic ... -
Geochemistry of komatiites and basalts from the Rio das Velhas and Pitangui greenstone belts, São Francisco Craton, Brazil: Implications for the origin, evolution, and tectonic setting
(Elsevier, 2017)"The Neoarchean Rio das Velhas and Pitangui greenstone belts are situated in the southern São Francisco Craton, Minas Gerais, Brazil. These greenstone belts were formed between ca. 2.79–2.73 Ga, and consist mostly of mafic ... -
Paleomagnetic pole positions and geomagnetic secular variation from the Cretaceous Ponta Grossa dike swarm (Brazil)
(2015)"A detailed paleomagnetic and rock magnetic investigation has been carried out on the Early Cretaceous Ponta Grossa dike swarm in southern Brazil. This formation seems an excellent target for paleomagnetic study. The dikes ... -
Petrogenetic and tectonic implications of major and trace element and radiogenic isotope geochemistry of Pliocene to Holocene rocks from the Tacaná Volcanic Complex and Chiapanecan Volcanic Belt, southern Mexico
(Elsevier, 2018)"New major and trace element, and Sr, Nd and Pb isotope data for samples from the Volcán Tacaná, along with the published data from the Tacaná Volcanic Complex (TVC) and Chiapanecan Volcanic Belt (CVB), were used to better ... -
Reappraisal of Los Humeros Volcanic Complex by New U/Th Zircon and 40Ar/39Ar Dating: Implications for Greater Geothermal Potential
(American Geophysical Union, 2018)"Longevity and size of magmatic systems are fundamental factors for assessing the potential of a geothermal field. At Los Humeros volcanic complex (LHVC), the first caldera-forming event was reported at 46040 ka. New zircon ... -
Role of unsaturated soil above a heavily contaminated aquifer in the natural attenuation of arsenic
(EDP Sciences, 2019)"Large attenuation of arsenic is observed in a shallow aquifer in central Mexico, where the concentration decreases from 91.5 to 11.3 mg/L, over 1.3 km horizontal distance. To investigate possible mechanisms of attenuation ...
