Summary Metasedimentary gneisses of the Proterozoic Grand Forks Group experienced rapid hightemperature, ~2.5kbar exhumation in the late Paleocene to early Eocene, coincident with orogenic collapse in the hinterland of the Canadian Cordillera. The migmatitic paragneisses were metamorphosed to upper amphibolite facies, Sil+Kfs zone (abbreviations after Kretz, 1983) at c. 84±3 Ma (Laberge and Pattison, 2007), and experienced near isothermal decompression at 750-725°C (Cubley and Pattison, 2009… CONTINUE READING
