Granodiorite weakly deformed without reaction at mid greenschist conditions; feldspars fractured, quartz deformed by regime 2 dislocation creep.
Overview of weakly deformed granodiorite. Quartz and biotite have deformed by intracrystalline plasticity processes, evident from the undulose extinction, subgrain formation, and dynamic recrystallization. Feldspars have deformed by fracturing.
