1 :   
Comments: Sample Type: Ol-plg phyric _Pillow basalt. Mineralogy: Plag-oliv. Weathering: light to moderate. Glass condition: Some moderately fresh glass. 1 bucket. 55-1 glass for probe, DG and KJ. 55-2 glass for probe and KJ. Samples placed in bucket. small amount of station glass from dredge bag, subsampled by DG.Moderately altered plagioclase-olivine phyric pillow basalts with small amount of glass. Type 1 of this dredge.

Comments: Sample Type: Ol-plg phyric _Pillow basalt. Mineralogy: Plag-oliv. Weathering: light to moderate. Glass condition: Some moderately fresh glass. 1 bucket. Sampled placed in glass bucket.Moderately altered plagioclase-olivine phyric pillow basalt with a large plagioclase megacryst. Distinct from type 1 of this dredge by lack of any glass.
