Sediment Sampling details

Device used: Dredge - unspecified

ContentsTop (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.
