Description: 4 bags + lab samples. Approx. 600 lbs (270 kgs) of rocks. South side of north seamount dredged. Of the samples obtained, four thin sections were made: A1 - Augite, plagioclase, olivine main mineral components. Subophitic texture. Plag. Laths enclosed by subhedral augite in a fine grained intergranular to hyalopilitic groundmass containing glass + opaques. Olivine highly altered. Olivine, plag, augite basalt - Alkali basalt. B1 - This plag. laths, Olivine rimmed w/ iddingsite, corroded or resorbed augite, intergranular opaques, vesicle filling carbonates. Vesicular texture, pilotaxitic to subvariolitic plag.texture. Hawaiite or vesicular Alkaliolivine basalt. C1 - Highly altered olivine, Augite, plagioclase intergrowths w/ Augite. Texture - subophitic to subvariolitic plag. w/ augite with glassy interstital groundmass. Fine grained Iddingsite - plag basalt. D1 - Subhedral augite, altered plag. laths, chert nodules or vesicle fillings (?), iddingsit; texture subvariolitic plag laths, vesicles filled; w/ chert or chert nodules entrained in flow; Highly altered alkali-olivine basalt or Iddingsite-plag basalt. In addition, there were several carbonate cemented breccias which may be tectonic judging from variable fragment types. Rocks included - volcaniclastic breccia (w/ vesicular basalt cobbles) and chert nodules surrounded by phosphatized (?) carbonate.
