| Text Description: | Hand sample; >20g. Older lava up along small ridge behind East Point seismic sta. Likely a ol, cpx,pl BA, A. This unit ~8 m thick (bottom obscurred) w/ large equant cochoidal frac blocks up to 1.5-2m among smaller faceted boulders and inter-boulder red oxidized flow margin (red oxidation is brick-red; similar to cone B at Okmok and other basaltic scoria). This outcrop ~same as one ot N and could well be lobate margin of large AA flow. [Blue sky, light wind (no white-caps). Constant calls of least auklets (cicada-like) and more barking/squeaking/gull like call of whiskered auklet.] Dark gray (60%k) basalt. Phenocrysts of plag (2mm) and cpx (3mm) in coarsely crystalline gms. Phenocrysts hard to distinguish from gms because of crystallinity. Phenocrysts maybe 20%, but abt gms xls. Contains a few cm-scale gabbroic inclusions. |
