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. eng open access Nd isotopic heterogeneity in late-Hercynian granitic plutons from Central Spain Heterogeneidades isotópicas de Nd en plutones graníticos tardi-hercínicos de la región central española journal article
