Figure F9. Photomicrographs of granoblastic basalt. A. Strongly granoblastic basalt of Unit 1256D-96A showing a relict intergranular texture (Sample 335-1256D-235R-1, 11–12 cm [Piece 1]; Thin Section 2) (cross-polarized light). B. Completely granoblastic basalt of Unit 1256D-96B showing a relict plagioclase microphenocryst with pyroxenes and oxide inclusions in its core (Sample 335-1256D-236R-1, 38–39 cm [Piece 7]; Thin Section 5) (plane-polarized light). Yellow-pink chain of orthopyroxene (Opx) crystals represents a metamorphic vein.
