The Cretaceous Nuevo Rosarito plutonic suite is located in the southern part of the Peninsular Ranges batholith (~28.7 °N). It is hosted by a suite of Jurassicgranitoidrocks datedat 151.6Ma (U-Pb single zircon ages) and by Late Jurassic - Early Cretaceous…

A ca.30 m thick tephra-sediment sequence from the north-eastern Basin of Mexico (Pachuca sub-basin, central Mexico) is investigated for stratigraphy and multi-element geochemistry to understand the tephrochronology, provenance and conditions of chemical weathering duringLate Quaternary. Chemical compositions of tephra layers…

Analogous to chemometrics, geochemometrics can be defined as the science resulting from the combination of statistics, mathematics and computation with geochemistry. This term in Spanish -geoquimiometría- has already been explicitly used in the literature. Here I elaborate on the numerous…

Major, trace and rare earth elements (REE) concentrations in limestone beds of the Canova and El Caloso members of the Mural Formation in the Cerro Caloso Pitaycachi area were measured to understand the depositional conditions and source of REE. Contents…
