Text Description:
Qccd - Smaller satellite centers (Pleistocene). Dike. Light-colored dike up to 7 m wide that appears to originate in cinder code (Qcc) and extend more than 2 km sw to Open Bight valley. Rock is a light brownish gray, porphyritic trachyte (67.8% SiO2) containing phenocrysts of plagioclase (5-10%, 3 mm), orthopyroxene (2-5%, 1.5 mm) and clinopyroxene (1-2%, 1.5 mm) in a trachytic groundmass containing 1-2% opaque minerals.
