Abstract New whole-rock geochemical and detrital zircon U–Pb Lu–Hf data of metasedimentary sequences the Silvretta Nappe, Orobic Alps, Strona-Ceneri Zone, Gotthard Massif Venediger Nappe are presented. These units seem to share a common early middle Paleozoic geological record, which has alternatively been interpreted as result intraplate or orogenic processes. Detrital mainly indicate late Edi...

Two techniques of possible interest to those concerned with tracing the origins and disper...
