Figure F102. High-temperature crystal-plastic microstructures in cross-polarized light. Scale bars are 2 mm. A. Olivine (Ol) porphyroclast, with subgrains, bordered by recrystallized olivine grains, in a matrix of fine-grained recrystallized plagioclase. Sample 176-735B-135R-1 (Piece 2E, 98-102 cm). B. Plagioclase (Pl) porphyroclast, bordered by recrystallized plagioclase grains, next to an elongate olivine porphyroclast (Ol). Sample 176-735B-104R-2 (Piece 6B, 45-47 cm). C. Mylonitic (1) to ultramylonitic (2) foliation, with a matrix of recrystallized plagioclase, olivine, and pyroxene. The mylonite contains plagioclase (Pl), pyroxene (Px), and oxide (Ox) porphyroclasts or ribbons. The pyroxene porphyroclasts have very elongated recrystallized tails. Sample 176-735B-155R-6 (Piece 5B, 118-122 cm). D. Close-up of (C), showing a small plagioclase ribbon, a pyroxene (Px) porphyroclast with recrystallized mantle and tails, and a Fe-Ti oxide ribbon, in a fine-grained recrystallized matrix. Sample 176-735B-155R-6 (Piece 5B, 118-122 cm).
