| Contents | Top (m) | Base (m) |
|---|---|---|
| Dull black microvesicular lava, sparsely plagioclase phyric (10%) with some rounded clinopyroxene. Looks like a ?folded? lava. Includes some fine grained clasts that might be chilled. | ||
| As for 60-01, but without the clasts. | ||
| Dark grey-green microvesicular lava, sparsely phyric with 15% plagioclase phenocrysts. Also has rounded clinopyroxene phenocrysts in clusters with plagioclase and rarely olivine clustered with plagioclase. | ||
| Green-grey banded lava, microvesicular. Contains clasts that are less vesicular. Somewhat glassy. ~10% plagioclase phenocrysts with a few clinopyroxenes. | ||
| As for 60-01, but dark grey. | ||
| Banded light-dark grey lava. Vesicle trains in separate bands. Sparsely plagioclase phyric (10%), with some clinopyroxene and rare olivine (despite lighter color). | ||
| Pale pink to pale grey aphyric pumice. Devitrification banding to dark grey on one piece. Weakly weathered surface. | ||
| As for 60-01, but olivine phenocrysts are present. | ||
| Medium grey lava, 10% plagioclase phenocrysts with some clinopyroxenes that seem out of equilibrium. A large olivine xenocryst on the exterior surface. | ||
| As for 60-01, but without the vesicles. | ||
| As for 60-02, but a dark grey lava. | ||
| Grey lava, ~10% plagioclase phenocrysts with trace olivine and clinopyroxene. Microvesicular. Weathered grey-green surface. | ||
| Large block of glassy ?folded? lava containing lighter grey clasts of less vesicular lava. Similar to 60-01, being sparsely plagioclase phyric with lesser clinopyroxene. | ||
| Shiny black lava with vesicle bands giving a layered appearance. Sparsely plagioclase phyric (10%) with more clinopyroxene than the other units. |
