Text Description:
Juvenile clast from pyroclastic-flow deposit. Sample of pilotaxitic to hyalopilitic lava containing plagioclase, two pyroxenes, large hornblende grains with substantial opaque rims, and rare amounts of both rounded quartz grains and large anhedral olivine grains. (Texture: Vitrophyre; groundmass <0.2 mm, foliated, plagioclase > clinopyroxene > opaque; microvesicular; hornblende reacted and oxidized. Alteration: None)
