(2013-06)"The 1.5-Ma Adeje Formation in SW Tenerife contains an ignimbrite sheet with remarkable textural and chemical complexity. A basal Plinian pumice-fall layer is overlain by a partly welded compound ignimbrite in which ... -
Litoestratigrafía, petrografía, y geoquímica de la Toba Llano, y su relación con el cráter El Xalapazco, Caldera de Los Humeros, Puebla
(2016)"Debido a la situación energética actual, a nivel global hay un gran interés por la migración a energías más limpias. Tal es el caso de la energía geotérmica, la cual se aprovecha a partir del calor procedente del interior ... -
Magnetic characteristics of fracture zones and constraints on the subsurface structure of the Colima Volcanic Complex, western Mexico
(GeoScienceWorld, 2010)"Detailed magnetic anomaly surveys over the central and southern sector of the Colima rift, western Mexico, are used to investigate the subsurface structure and faults and/or fractures in the volcanic terrains formed by ... -
Modeling of groundwater flow and water use for San Luis Potosí Valley aquifer system
(2014)"Land use changes are currently one of the indisputable factors in the alteration of processes and cycles of the aquifer system in the San Luis Potosí Valley. Due to its importance, is considered indispensable to investigate ... -
Morphology and Solubility Products of Calcium Arsenates Found in Arsenic Contaminated Soils in an Abandoned Smelter
(2013)"The dissolution of calcium arsenates in residues released on the premises of an inactive smelter has caused high levels of arsenic pollution in the adjacent down-gradient 6 km of a perched aquifer, reaching up to 158 mg/L ... -
Morphometric and hypsometric analysis in the Tierra Nueva Basin, San Luis Potosí, México
(2017)"In areas with long periods of drought, it is essential to implement strategies to manage the available water resource. Tierra Nueva Basin is affected by this situation, consequently the farm production and livestock ... -
Paleozoic exotic blocks of the crimean mountains: stratigraphy and origin
(2014-08)"Based on numerous geological data obtained by the authors for several decades, the stratification of Permian and Carboniferous ancient and exotic blocks of Crimean Mountains is performed. The sequence of geological events ... -
Petrogenesis of voluminous silicic magmas in the Sierra Madre Occidental large igneous province, Mexican Cordillera: Insights from zircon and Hf-O isotopes
(Geological Society of America, 2022)"Combined Hf-O isotopic analyses of zircons from tuffs and lavas within the Sierra Madre Occidental (SMO) silicic large igneous province are probes of petrogenetic processes in the lower and upper crust. Existing petrogenetic ... -
Potential fields modeling of the Serdan Oriental basin, Eastern Mexico
(Elsevier, 2017)"In the eastern portion of the Trans-Mexican Neovolcanic Belt a group maars, rhyolitic domes, and cinder cones are scattered within the Oriental-Serdán basin. They are flanked by large polygenetic volcanoes. We use ... -
Precambrian plate tectonic setting of Africa from multidimensional discrimination diagrams
(Elsevier, 2017)"New multi-dimensional discrimination diagrams have been used to identify plate tectonic setting of Precambrian terrains. For this work, nine sets of new discriminant-function based multi-dimensional discrimination diagrams ... -
Quality assessment of irrigation water related to soil salinization in Tierra Nueva, San Luis Potosí, Mexico
(2016-12)"Soil salinization is a complex process resulting from the interaction of several factors, mainly quality of water used for irrigation, which deteriorates by aquifer overexploitation, and changes in rainfall patterns and ... -
Quality indices of groundwater for agricultural use in the Soconusco, Chiapas, Mexico
(2017)"In Soconusco, Chiapas, in spite of the high availability of surface water, it is resorting to the use of groundwater. Knowledge about the quality of surface or groundwater used to irrigate crops in that region is low. ... -
Recent advances in understanding the terminal Ediacaran Earth-life system in South China and Arctic Siberia
(CSIC, 2019)"The terminal Ediacaran contains dramatic changes in biogeochemical cycles, many of which are closely coupled with evolutionary transitions in the corresponding fossil records. Dynamic redox conditions may have caused a ... -
Rock magnetism and microscopy of the Jacupiranga alkaline-carbonatitic complex, southern Brazil
(Springer, 2009)"This study of the Cajati deposit provides evidence that the ore was neither purely hydrothermal, nor volcanic in origin, as previous workers have proposed. The ores were formed from magnetite-rich magmas, hydrothermally ... -
