1 :   
Comments: Sample Type: Plag phyric_Pillow basalt. Mineralogy: Plagioclase. Weathering: Moderate. Glass condition: Notable Mn/Fe oxide coatings, some glass. 2 buckets. Glass was separated from each sample for KJ. DG has a subsample of 35-8. Probe glass was taken from 35-1 thru 35-4, & 35-8. Rocks were placed in two buckets. Plagioclase phyric pillow basalt fragments that are moderately altered. Glass has minor amount of plagioclase phenocrysts. Small amount of glass on each sample. Type 1 from this dredge.

Comments: Sample Type: Basalt glass. Mineralogy: Plagioclase. Weathering: Moderate. Glass condition: Notable Mn/Fe oxide coatings. 2 buckets. Samples were placed in the glass bag for DR35. Probe glass was taken from 35-9. There is also a minor amount of bulk glass in glass bag. Small pieces of glass that have minor plagioclase phenocrysts and a Mn-Fe coating. Type 2 from this dredge.
