Figure AF1. (A) Intergranular textures from Unit 1256D-77 (Thin Section 30; Sample 312-1256D-189R-1, 68–69 cm) (field of view [FOV] = 4.8 mm; plane-polarized light) sometimes developing to (B) “true” subophitic textures (Thin Section 30; Sample 312-1256D-189R-1, 68–69 cm) (FOV = 2.4 mm; cross-polarized light). C. Fibrous actinolite with abundant tiny oxide grains replacing clinopyroxene (Thin Section 30; Sample 312-1256D-189R-1, 68–69 cm) (FOV = 0.6 mm; plane-polarized light). Light-colored clinopyroxene patches, especially in plagioclase at upper left, may represent the shallowest occurrence of secondary clinopyroxene.
