Fact sheet
Description: 

14235 is an olivine vitrophyre containing ~20% equant subhedral to euhedral phenocrysts of olivine (0.2-0.4 mm) heterogeneously distributed in the opaque groundmass as glomerophyric aggregates. Small chromite grains with attached metallic iron grains are found in the groundmass or attached to the rims of the olivine phenocrysts. Olivine includes spherical melt inclusions. The fine-grained opaque matrix is made of microlites of aluminous titanaugite, ilmenite and plagioclase. Rotation on shows a euhedral olivine crystal containing a large melt inclusion.
