Phylogenetic diversity of methyl-coenzyme M reductase (mcrA) gene and methanogenesis from trimethylamine in hypersaline environments
(2012)"Methanogens have been reported in complex microbial communities from hypersaline environments, but little is known about their phylogenetic diversity. In this work, methane concentrations in environmental gas samples were ... -
Physicochemical characterization, elemental speciation and hydrogeochemical modeling of Santa Lucía peloid used for therapeutic uses
(Centro de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México,, 2018)"Santa Lucia peloid is a sediment, extracted from salt mines, used in pelotherapy in Cuban primary health care services. Therefore, in addition to classical quality control analyses of total metal concentrations in sediments, ... -
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 ... -
Potential Flood Risk in the City of Guasave, Sinaloa, the Effects of Population Growth, and Modifications to the Topographic Relief
(MDPI, 2022)"The coastal city of Guasave, Sinaloa, located on the Mexican Pacific coast, is subject to extreme precipitation events, which have caused flooding with damage to the city’s infrastructure. The factors that influence ... -
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. ... -
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 ... -
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 ... -
Removal of Cu, Cd, Pb and Zn from Contaminated Soil by Using Plant-Based Surfactants, Sapindus mukorossi L (Soapnut) and Acacia Concinna (Shikakai)
(IJESD, 2019)"The performance of two plant-based surfactants in the removal of heavy metals (Cu, Cd, Pb and Zn) from soil was studied ex-situ. Experimental parameters were: six soil-solution ratios (1:10, 1:20, 1:30, 1:40, 1:50 and ... -
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 ... -
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 ... -
Sand waves generation: a numerical investigation of the Infiernillo Channel in the Gulf of California
(2016-07)"The effect of the coastal geometry on sand bed forms generation has been investigated for a tidal dominated area. Different hypothetical geometries of coastal channels with flat bottoms and unlimited sediment availability ... -
Síntesis de arseniatos de calcio (Guerinita, haidingerita y farmacolita) morfológicamente similares a los encontrados en suelos contaminados
(2017)"En el acuífero somero de Matehuala y Cerrito Blanco, en el estado de San Luis Potosí, México, se han reportado concentraciones de hasta 158 mg/L de arsénico cuya movilidad ha podido ser representada por la disolución de ... -
Southward migration of magmatic activity in the Colima volcanic complex, Mexico: an ongoing process
(2015)"The Colima Volcanic Complex trends in a nearly N-S direction in western Mexico, and one of its structures, Colima volcano, is the most historically active volcano in the country. Immediately to the N, there is another ... -
Spatio-Temporal Distribution of Deep Convection Observed along the Trans-Mexican Volcanic Belt
(MDPI, 2021)"Complex terrain features—in particular, environmental conditions, high population density and potential socio-economic damage—make the Trans-Mexican Volcanic Belt (TMVB) of particular interest regarding the study of deep ... -
Statistically coherent calibration of X-ray fluorescence spectrometry for major elements in rocks and minerals
(Hindawi Publishing Corporation, 2018)"We applied both the ordinary linear regression (OLR) and the new uncertainty weighted linear regression (UWLR) models for the calibration and comparison of a XRF machine through 59 geochemical reference materials (GRMs) ... -
Subduction of the Rivera plate beneath the Jalisco block as imaged by magnetotelluric data
(2013-08)"Two magnetotelluric (MT) profiles perpendicular to the trench provide information on the subduction of the Rivera plate under the Jalisco block (JB). The geometry of the subducting slab is inferred by the anomalous conductor ... -
