GRD047DS0 Basalt Quartz and epidote veins. Philippines 1 Camp Elliott
GRD047ES0 Basalt Fine grained crystallites of plagioclase, radiating needles. Red vein through center with some colorless mineral included and associated opaques. Poorly formed tiny ep. opaque rich and opaque poor banding perpendicular and inclined to red vein. Philippines 1 Ritter 154, 28 G
GRD047FS0 Basalt Altered basalt. Plagioclase, very highly altered in random and radiating lathes 1-2mm long. Remnants of birefringent something, probably olivine, cpx, serp present. Opaques, blocky, (mt) sericite is all that is left of most plag. Philippines 1 Camp Elliott
