Photographs and microphotographs of metamorphic rocks: a) metapyroxenite enclave in granodiorite; b) metatexitic amphibolite; c) amphibolite and paragneiss enclaves in diffuse contact with heterogeneous biotite granite interpreted as a diatexite. Cross polarized view of (d) metapyroxenite with heterogranular granoblastic microstructure; (e) amphibolite with hornblende-plagioclase-biotite and interstitial quartz; (f) amphibole and pyroxene paragneiss with granoblastic heterogranular microstructure; and (g) biotite and amphibole paragneiss grano-lepidoblastic microstructure.
