Figure F51. A. Sample 176-735B-110R-2 (Piece 3C, 101-104 cm): large euhedral grain of titanite in a diopside vein. The tip of the titanite crystal projects into a patch of chlorite. B. Sample 176-735B-144R-6 (Piece 5B, 89-92 cm): large crystals of green amphibole and titanite in a felsic vein. C. Sample 176-735B-99R-4 (Piece 6, 108-111 cm): mymekitic intergrowth of quartz and feldspar in a felsic vein. D. Sample 176-735B-157R-5 (Piece 8, 134-140 cm): euhedral zircon crystal associated with large crystals of brown biotite in a sheared zone in olivine gabbro. Scale bars = 0.5 mm.
