Geochronologic and geochemical data of plutonic rocks from 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including published articles, thesis, internal reports from mining companies, and to a large extent come from unpublished information generated by the working group (CONACYT Research Grant 49528-F).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. The Cretaceous-Eocene Mexican Magmatic Arc: Conceptual framework from geochemical and geochronological data of plutonic rocks本数据库所收录的数据，用于明确所谓白垩纪-始新世墨西哥岩浆弧（Cretaceous-Eocene Mexican Magmatic Arc，缩写CEMMA）的形成时序、岩石组成与岩石成因特征。该岩浆弧横贯墨西哥西部全域，对其开展研究对于阐明北美西南部的构造演化过程至关重要。 本数据集的数据均经严谨筛选与整理自各类文献，包括已发表的学术论文、学位论文、矿业公司内部报告，且在很大程度上来源于本工作组依托CONACYT研究资助项目（编号49528-F）所产生的未公开资料。凡因所用实验方法存疑、或数据信息存在矛盾的不可靠数据，均未被纳入本数据库。 白垩纪-始新世墨西哥岩浆弧：基于深成岩地球化学与年代学数据的概念框架
