| Comment | Sample is very light brown devitrified partially welded tuff with scarce to common very light gray pumice to 13 mm that contains abundant tiny acicular groundmass mafics, probably acmite. Common felsic phenocrysts are dominated by feldspar to 7 mm, but smoky quartz is evident. Scarce mafics are black amphibole, very dark green clinopyroxene, and black to red olivine pseudomorphs. Lithics to 6 mm are scarce. |
