BP9 has a full slide scan available. Imaged by K. Hardy and M. Leclerc, ANU.
Wholly non-calcareous, poorly sorted andesitic sand temper made up dominantly of vitric, microlitic and some felsitic volcanic lithic fragments, feldspar is plagioclase. Coarseware. Clinopyroxene and orthopyroxene.
Type B VST. Terrigenous andesitic (non-quartzose) volcanic sand temper. Clinopyroxene dominant, but minor orthopyroxene.
Wholly non-calcareous, poorly sorted andesitic sand temper made up dominantly of vitric volcanic lithic fragments, feldspar is plagioclase. Coarseware.
