Early Ordovician ages of zircons from felsic rocks and a conglomerate clast, Frosta peninsula, Central Norwegian Caledonides
Gromet, L. Peter; Roberts, David (NGU Bulletin (450), Journal article, 2010)Zircons extracted from a felsic sheet in the bimodal, magmatic, Fånes complex of the Støren Nappe on Frosta peninsula yielded a U-Pb age of 488 \u00B1 5 Ma, interpreted as the age of crystallisation. A large clast of ... -
