Acadian Metamorphism in The Dunnage Zone of Southern Quebec, Northern Appalachians: 40Ar/39Ar Evidence For Collision Diachronism

Basic Information
Author: Tremblay Alain, Ruffet Gilles and Castonguay Sebastien
Description:Acadian Metamorphism in The Dunnage Zone of Southern Quebec, Northern Appalachians, 40Ar/39Ar Evidence For Collision Diachronism, Geological Society of America Bulletin, January 2000, v. 112, no. 1, p. 136-146. The comparison of Devonian tectonic fabrics in New England and southern Quebec suggests that progression in the timing and P-T conditions of Acadian peak metamorphism in both areas are the result of the irregular geometry of the collision zone and of the northward migration of metamorphic and structural fronts along the orogen.
