Sediment Sampling details
Device used: Dredge - unspecified
| Contents | Top (m) | Base (m) |
|---|---|---|
| Black microvesicular (<<1 mm) basalt. In addition to the microvesicles there are ~5% irregular vesicles mostly 2-3 mm across. Trace plagioclase and olivine phenocrysts. Surfaces are glassy with ropey texture and disaggregate into small plates. Discolored light grey beneath the glassy layer. Weakly weathered | ||
| Fine grained glassy material and hyaloclastite from the sediment pipes. | ||
| Black olivine-plagioclase basalt. 5% plagioclase 1-2 mm across and trace olivine 1 mm across. 15% large oval vesicles 3-8 mm across. Otherwise dense. Surface weathered brown. |
