IL_2_2
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.
IL_2_20
Sio style. CAUTION: Section less than 30microns. Pyroxene grains (5%) are generally less than 0.4 m in length. Plagioclase laths (5%) are less than 0.2 mm in length. There are some large volcanic rock fragments made up of abundant plagioclase laths, minor pyroxene and fine grained opaques in a hypocrystallne texture. Accessory iron oxide and red ferruginized clay pellets are also present. The clay is dark brown.
IL_1_18
Sio style. CAUTION: Section less than 30microns. This dark red to black sherd contains abundant quartz and plagioclase up to 0.1 mm in length. There are some large pyroxene and volcanic rock fragments up to 0.4 mm in length but these grains are only accessory.
