Figure AF2. A. Basalt from Unit 1256D-79 collected from junk basket (Thin Section 41; Sample 312-1256D-201G-1, 48–52 cm) (field of view [FOV] = 2.4 mm; plane-polarized light). Low-grade alteration suggests that it is derived from a shallower level in the hole. B. Probable quartz microdiorite consisting of clear quartz, cloudy plagioclase, greenish-brownish hornblende, and black Fe-Ti oxide (Thin Section 44; Sample 312-1256D-201G-1, 0–1 cm) (FOV = 0.6 mm; plane-polarized light). Fuzzy appearance reflects pervasive cataclastic recrystallization. C. Cataclasite derived from felsic microdiorite or similar lithology (Thin Section 44; Sample 312-1256D-201G-1, 0–1 cm) (FOV = 0.6 mm; plane-polarized light). Note the strong alignment of oxide grains.
