Sio style sherd. CAUTION: Section less than 30microns. Pyroxene grains range in size from 0.1 up to 0.7 mm in length. There are some ferruginized clay pellets, up to 2 mm in length. Minor plagioclase and iron oxide minerals are also present. The sherd also contains abundant fine grained quartz grains, less than 0.1 mm
Sio style sherd. "CAUTION: Section less than 30microns. Pyroxene crystals are angular and about 0.4 mm in diameter. They are unaltered and show prominent cleavage traces. Volcanic rock fragments essentially contain ferruginized glass, feldspar crystals and small plagioclase laths. Opaques, rounded red brown clay clasts, ferruginized fossil fragments and feldspar grains are minor components. The clay is dark brown.
Sio style. CAUTION: Section less than 30microns. in diameter. Volcanic rock fragments (<10%) are up to 0.5 rnn across and contain feldspar microlites, opaques and altered glass. Angular pyroxene crystals are accessory. Elongate and rounded pellets are devoid of inclusions. The sherd also contains some large (up to 2 nm in length) ferruginized fragments which also contain opaques and plagioclase. These may be broken pot fragments. Opaque minerals.
Sio style. CAUTION: Section less than 30microns. Pyroxene grains (<5%) are up to 0.3 mm in length. Red ferruginized clasts (<1%). Opaques and strongly altered volcanic rock fragments are accessory components. The sherd also contains less than 5% of fine grained angular quartz.
Sio style. CAUTION: Section less than 30microns. Pyroxene grains (10%) are generally less than 0.3 mm in length. There are several large (up to 0.8 mm) dark ferruginized clasts and minor weathered volcanic rock fragments and angular quartz grains.
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.
