Detail of granodiorite moderately deformed at mid greenschist conditions.
Higher magnification view of moderately deformed granodiorite sample shown in photo #70. Near the center of the image, a rigid and relatively undeformed plagioclase porphyroclast has produced a stress concentration in the adjacent quartz grain, which is more strongly deformed (more prominent subgrain formation) near the plagioclase than further away from it.
