Pressure-solution structures in a granite
Abstract
Syntectonic two-mica granites in northwest Spain have suffered regional Late Variscan shear deformation. The deformed Corcoesto granite shows a marked planar and linear fabric resulting from ductile behaviour and contains quartz veins at about 60° to the foliation. Offsets of these quartz veins along shear planes are commonly contrary to the general sense of shear and thus provide evidence for pressure-solution processes.
