Geochronological and geochemical data for plutonic rocks of the Cretaceous-Eocene Mexican Magmatic Arc (CEMMA)

The data provided in this database were used to establish the temporality, composition and petrogenetic aspects of the so-called Cretaceous-Eocene Mexican Magmatic Arc (CEMMA). This magmatic arc is continuous throughout western Mexico and its understanding is critical to elucidating the tectonics of southwestern North America. The data were carefully compiled from the literature, including published articles, thesis works of various degrees, internal reports from mining companies, and to a large extent come from unpublished information generated by the working group (CONACYT Research Grant 49528-F). Unreliable data in relation to the methodology used and those where the information was inconsistent were not included.
