|Comments: ||Sample Type: Pillow basalt. Mineralogy: Sparse Plagioclase in glass and rock. Weathering: Mn crust. ~50% of glass is fresh. 1 bucket. Recovery about 7 kg. Probe glass taken from both samples. Glass splits taken for KJ and DG from 33-1. Both samples in bucket. Type 1 from this dredge. 33-1 is glassy pillow toe with Mn coating and a glassy rind ~1cm thick completely surrounding an aphyric core containing sparse (<<1%) plag phenocrysts. About half the glass is still left on the archived rock sample. 33-2 similar as 33-1, most likely a chip.|

|Comments: ||Sample Type: pillow basalt. Mineralogy: Sparse Plagioclase and olivine in rock. Weathering: Moderate to heavy. Glass condition: Some fresh glass and Mn/Fe oxide coatings. 1 bucket. Recovery from dredge about 7 kg. Probe glass taken from sample. Glass seperated for KJ. Sample in bucket. 33-3 is an angular pillow basalt with a thin glass rind and yellow alteration staining. Sparse plagioclase and olivine phenocrysts in the rocks. Type 2 from this dredge.|

|Comments: ||Sample Type: Bulk glass. Mineralogy: Some of the glass contains plag phenocrysts. Weathering: Light to heavy. Glass condition: Some fresh glass and Mn/Fe oxide coatings. 1 bucket. Recovery from dredge 33 about 7 kg.Sample in bucket. Small amount of bulk glass. Some containing phenocrysts, some not. Most of the glass has a Mn coating.|
