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 Villaseca González, Carlos Barbero González, Luis C. Rogers, G. Reyes Hernández, Javier Santos Zalduegui, José Francisco Some Hercynian granitic plutons from Central Spain show variation in initial Nd isotopic ratios defining different trends with increasing silica content. 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. 2025-06-18T09:52:54Z 2025-06-18T09:52:54Z 2025-06-18T09:52:54Z 1997 journal article https://hdl.handle.net/20.500.14352/121476 0213-683X eng PB93-0295-CO2 Villaseca González, C. et al.
