Lithospheric-scale thrusts from the west Newfoundland ophiolite belt (White Hills Peridotite shear zone) and the south-western Grenville Province (Parry Sound shear zone) involve rocks of lower crustal and (or) upper mantle origin that exhibit intense crystal-plastic deformation of plagioclase, K-fe...
