 Text Description:
Rounded vesicular magmatic inclusion in 91CND16. Contains large phenocrysts of chromite-bearing olivine (but not plagioclase) in a vesicular groundmass of interlocking plagioclase, pyroxene, and olivine. Olivine basaltic andesite magmatic inclusion. Rounded magmatic inclusion in 91CND16 host with 40% vesicles, 20% olivine (up to 1.3 x 0.6 mm, and containing euhedral translucent brown chromite octahedral) in a holocrystalline matrix compose of subequal amounts of plagioclase (300 x 80 microns) and pyroxene (200 x 150 microns).
