Geochronology of Mexican mineral deposits. III: the Taxco epithermal deposits, Guerrero

Boletín de la Sociedad Geológica Mexicana, 2015
New 40Ar/39Ar (34.96 ± 0.19 Ma) and U-Pb ages (35.44 ± 0.24 and 34.95 ± 0.37 Ma) obtained in this study for the Calavera group of dikes, which predate intermediate sulfidation epithermal mineralization in the Taxco mining district, constrain the formation of such deposits to less than 34.96 Ma (latest Eocene).
