Sio style. CAUTION: Section less than 30microns. Pyroxene grains (<5%) are up to 0.3 mm in length. Angular quartz and feldspar grains make up about 10% of the sherd. These grains are generally small, <0.1 mm but range up to 0.2 mm. Opaque grains, (<5%) are subrounded and up to 0.4 mm in length. There are some minor rock fragments. The clay is red brown.
