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.engjournal articlehttps://sociedadgeologica.org/publicaciones/geogaceta/geogaceta-23-1997/open access552.3(460)"621.6"Sr and Nd isotopesHercynian granitesOpen/closed magnetic processesPetrología2506.13 Petrología Ignea y Metamórfica
