Abstract

Crustal thickening and widespread mid-crustal partial melting have inititated lateral flow after or concurrently with the emplacement of the Group 2 granodiorite. The lateral flow has reactivated large scale shear zones allowing the transportation of the Group 3 rocks from the lower crust to the upper-middle crustal detachment zone. The change in the degree of deformation at the exposed parts from undeformed, through local to pervasive is attributed to differences in the exhumation level. (C) 2016 Elsevier B.V.
