Eruptive chronology and tectonic context of the late Pleistocene Tres Vírgenes volcanic complex, Baja California Sur (México)
(Elsevier, 2018)"Based on a detailed geological map and stratigraphy aided by new Th-230/U-238 and P-206/U-238 age determinations we established the eruptive chronology of the Tres Virgenes Volcanic Complex (TVVC). The complex consists ... -
Boiling-over dense pyroclastic density currents during the formation of the similar to 100 km(3) Huichapan ignimbrite in Central Mexico: Stratigraphic and lithofacies analysis
(Elsevier, 2018)"A lithofacies analysis of the Huichapan ignimbrite has been undertaken to evaluate its depositional history from large pyroclastic density currents. The Huichapan ignimbrite is a massive ignimbrite sheet with a maximum ... -
Arsenic contamination in irrigation water, agricultural soil and maize crop from an abandoned smelter site in Matehuala, Mexico
(Elsevier, 2017)"Mobility of Arsenic (As) from metallurgical wastes in Matehuala, Mexico has been accounted for ultra-high concentration of As in water (4.8–158 mg/L) that is used for recreational purposes as well as cultivation of maize. ... -
Análisis de la estabilidad de nanotubos de carbono en función de la composición química del agua
(2019-09-04)"El estudio de nanotubos de carbono en agua se ha tornado relevante en los últimos años. No obstante, a la fecha, no existen estudios que analicen la estabilidad de los NTC en diferentes tipos de agua. Por tal motivo, se ... -
Geochronological and geochemical constraints on the genesis of Cu-Au skarn deposits of the Santa María de la Paz district (Sierra del Fraile, Mexico)
(Elsevier, 2018)"Cu-Au skarn deposits of the mining district of Santa María de La Paz are located in the Sierra del Fraile, in the northern part of San Luis Potosí, Mexico. Samples of four different intrusions and their related skarn ... -
