Abstract

This hypocrystalline thin section contains euhedral to subhedral phenocrysts of augite and eight-sided, rounded, phenocrysts of a colorless, moderate-relief, very weakly birefringent mineral, perhaps leucite, sodalite, or analcite. The groundmass of indistinct, microlitic k-feldspar and pyroxene is rich with equant opaques and cloudy in appearance.
