Figure F215. Fine-grained basalt from Unit 1256D-68 with hypocrystalline intersertal to radiate textures. A. Plagioclase as graphophyric intergrowth with clinopyroxene in clusters of radiating acicular crystals with partly cylindric hollow cores. (Thin Section 6; Sample 312-1256D-174R-1, 130–134 cm) (field of view [FOV] = 2.4 mm; plane-polarized light). B. Same as A; cross-polarized light. C. As in A, but finer grained (Thin Section 6; Sample 312-1256D-174R-1, 130–134 cm) (FOV = 4.8 mm; plane-polarized light). D. Same as C; cross-polarized light.
