| Large aphyric pillow with sparse occasional plagioclase microphenocrysts. 10% vesicles (+/- in bands), generally spherical and 1-2 mm in diameter. Glassy outer surface is red-brown. About ~200 g of glass was removed. A large sub-sample was archived in its own bucket. Appears basaltic rather than andesitic. | ||
| Two walnut-sized pieces of glassy black lava with tubular vesicles. | ||
| Two smaller (500 g each) pillow pieces. Characterised by very smooth glass surfaces- shiny black. Aphyric. Vesicular (15%) evenly distributed from <1 mm to <<1 mm across. | ||
| Very similar set of three pillows. Archived as a subset in its own bucket with the glass removed. |
