| Contents | Top (m) | Base (m) |
|---|---|---|
| Black aphyric shiny glassy lava, dominated by elongate vesicles. Contains areas that are transitional to mid-dark grey almost woody pumice. Sub-types were distinguished by vesicularity. The dominant type has 5-10% elongate vesicles to 1 cm long. | ||
| Maybe an older flow, as these blocks have a continuous thin black MnOx coating. | ||
| A denser variant, less prone to fracture than 27-02. | ||
| A less vesicular variant, with ~5% small flow/aligned vesicles ~1 mm in diameter. Type specimen contains a single inclusion of plagioclase-olivine-clinopyroxene(?) in apparent reaction relationship with groundmass. |
