Abstract

The high quantity of vesicles in this thin section keep the phenocrysts of plagioclase, clinopyroxene, and olivine well separated. While the clinopyroxene is euhedral in shape, the other two phases are more subhedral. Plagioclase phenocrysts have a sieve texture. The groundmass is mostly glass, with a few, moderately sized grains of plagioclase.
