1 :    IGSN IEUHM007H  
Lithology/Mineralogy: igneous (extrusive/volcanic), basalt
Comments: Sample Type: Small basalt cobbles. Mineralogy: Aphyric. Weathering: Light to moderate. Glass condition: Some fresh glass and Mn/Fe oxide coatings. 1 bucket. Glass taken from 36-1 and 36-2 for KJ and for the probe. 36-1 was subsampled for DG. 36-3 subsampled by KN. Rocks placed in bucket with rocks from dredge 35. Three small basalt cobbles with thin glass rinds. The glass is lightly altered while the rock appears moderately weathered. Type 1 from this dredge.
2 :    IGSN IEUHM007I

Comments: Sample Type: Basalt glass. Mineralogy: Aphyric. Weathering: Light to moderate. Glass condition:Mn/Fe oxide coatings. Entire sample will be used only as a probe sample. Small piece of glass that in all liklihood came off one of the other samples. Has Mn coating and is aphyric. Type 2 from this dredge.
