There is a decoupling between the Sr and Nd isotopic systems as these plutons present homogeneous initial Sr ratios. Magmatic processes could explain this Nd isotopic disequilibrium; it is suggested that Nd-bearing restitic or early precipitating accesory phases could control the Nd isotopic heterogeneity of the granites}, publisher = {Sociedad Geológica de España}, title = {Nd isotopic heterogeneity in Iate-Hercynian granitic plutons from Central Spain}, title = {Heterogeneidades isotópicas de Nd en plutones graníticos tardi-hercínicos de la Región Central Española}, author = {Villaseca, Carlos and Barbero, Luis and Reyes, J. and Santos Zalduegui, José Francisco}, }
