Text Description:
A xenolith in olivine andesite from a spatter ridge. The xenolith is equigranular with fractured, anhedral olivine, some has iddingsite alteration and the edges appear to be partially melted (amorphous brown cryptocrystalline material). There may be some clinopyroxene present. Plagioclase grains are fractured, subhedral to anhedral, and a few have corroded edges (melt?).
