| Black glassy lava with hackly and agglutinated exterior surfaces. Elongate flow aligned vesicles ~20% up to 3 mm in diameter and several cm long. Scattered small (~1 mm) light green olivine (<2%) +/- sheafs of plagioclase (?) and olivine-plagioclase clots (all <<2 mm). | ||
| Same as 34-01, but older in appearance with a thin black MnOx coating and duller sheen. | ||
| Irregular glassy spatter-like material. Abundant transitions to grey pumiceous areas. Abundant gas cavities. Probably a textural variant of 34-01. |
