Sediment Sampling details

| Contents | Top (m) | Base (m) |
|---|---|---|
| Fresh black basalt, 10% plagioclase phenocrysts to 2 mm across. Highly vesicular core to pillow (50% vesicles; up to 1 cm across) grading to weakly vesicular glassy crust (10% vesicles; <1 mm across). Glassy crust is greenish grey and dense. Exterior surface is orange palagonised glassy lava, sometimes with well developed ropey texture. Rare dioritic xenoliths. | ||
| Blue-grey non-vesicular dense plagioclase andesite. 20% plagioclase phenocrysts to 4 mm across. Outer 5 mm of clast is weathered brown. Occurs as a xenolith within 62-01 type lava. | ||
| As for 62-01, but trace clinopyroxene phenocrysts ~1 mm across. Probably these occur at trace levels in all blocks. |
