ContentsTop (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.
