Microlitic fragments in which birefringent plagioclase microlites are embedded in tan to brown volcanic glass, felsitic fragments composed of microgranular quartz-feldspar mosaics formed by devitrification of felsic volcanic glass, and vitric or glassy fragments of tan to brown (or red) volcanic glass.
WD_44_18
Hybrid partially placered sand temper.
