Nuevos datos geocronologicos Rb - Sr del pluton de Campanario - La Haba (batolito de Los Pedroches, Extremadura)

Abstract

A Rb-Sr whole-rock array corresponding to a circa age of304 ± 6 Ma has been obtained for the peraluminous granite of Campanario - La Haba pluton. The Sr initial ratio of 0.70619 ± 0.00034 of this pluton is less radiogenic than those typical S granites of metasedimentary crustal origin, indicating that this granite may not have been exclusively derived from crustal sources. The emplacement occurred during late-Hercynian deformation events
