Figure F6. Moderately olivine-phyric basalt (Thin Section 89; Sample 345-U1415K-1R-1, 52–54 cm [Piece 10]). A. Glomerocrysts of olivine (Ol) and plagioclase (Pl) in an intergranular matrix consisting of olivine, plagioclase, and clinopyroxene (Cpx). B. Globular sulfide (Sul) within olivine. The position is shown in A. C. Spinel (Spl) with fresh and altered olivine phenocrysts. (Ol) = altered olivine. D. Complex zoning of plagioclase. A and D are under crossed polars; B is in reflected light; C is under plane-polarized light.
