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 ... -

(2007)"El relleno sedimentario del graben de Villa de Reyes (San Luis Potosí, México) está formado por sedimentos clásticos del Cenozoico tardío que alojan al acuífero de Villa de Reyes. El estudio de las propiedades eléctricas ... -
Surface and physicochemical characterization of phosphates vivianite, Fe2(PO4)3 and hydroxyapatite, Ca5(PO4)3OH
(2009-08)"Hydroxyapatite is a calcium phosphate in the apatite group. It has numerous applications due to its particular properties including the sorption of metallic ions. This makes it useful for the treatment of contaminated ... -
The Greater Himalayan thrust belt: Insight into the assembly of the exhumed Himalayan metamorphic core, Modi Khola valley, central Nepal
(American Geophysical Union, 2020)"Strike-parallel discontinuities within the Himalayan metamorphic core are interpreted to reflect thrust-sense movement. There is, however, disagreement on the nature and sense of movement across one such structure in ... -
The Ilopango Tierra Blanca Joven (TBJ) eruption, El Salvador: Volcano-stratigraphy and physical characterization of the major Holocene event of Central America
(Elsevier, 2019)"The Ilopango caldera is the source of the large Tierra Blanca Joven (TBJ) eruption that occurred about 1.5 ka years ago, between ca. AD270 and AD535. The eruption dispersed volcanic ash over much of the present territory ... -
The labile fractions of metals and arsenic in mining?impacted soils are explained by soil properties and metal source characteristics
(Wiley, 2020)"Isotopically exchangeable metals in soil, also termed labile metals, are reversibly bound to soil surface and are a better index of the environmental risk of the metals than are their total concentrations. In this study, ... -
The VISHMOD methodology with hydrochemical modeling in intermountain (karstic) aquifers: case of the Sierra Madre Oriental, Mexico
(2014)"Hydrogeochemistry can be studied qualitatively using graphics such as scatter plots and Piper, Durov, and Schoeller diagrams, among others, and quantitatively by applying mass balance mixing models. The VISHMOD methodology ... -
Timing of speleogenesis of Las Karmidas Cave (Mexico): first description of pseudokarst developed in ignimbrite
(Union Internationale de Spéléologie, 2017)"Las Karmidas Cave (Puebla State, Mexico) is an unusual type of pseudokarstic cavity generated by piping and erosive processes within the contact of a diamicton and an overlying Quaternary ignimbrite. Morphological evidence ... -
