Isotopic evidence for the provenance of some Caledonian granites

A combined Nd- and Sr-isotope study of Caledonian granites in Scotland and northern England demonstrates the importance of continental crust in their petrogenesis and places limits on the involvement of contemporary mantle-derived material

Sr, O, and Pb isotope evidence for origin and evolution of Etive Igneous Complex, Scotland

A multi-isotope approach has been applied to the origin of one of the largest and latest Newer Granite complexes of the Scottish Caledonides. Contributions from both mantle and unexposed late Proterozoic lower continental crust are recognized, indicating that granite magmatism is a mechanism for both primary crustal growth and reworking of older crustal rocks
