Figure F22. Magmatic textures (under crossed polars). A. Olivine gabbro showing deformation twins in a relatively large and only weakly annealed, zoned plagioclase crystal (Sample 345-U1415I-3R-4, 16–19 cm [Piece 2]). B. Gabbro showing a highly deformed plagioclase crystal with undulose extinction (Sample 345-U1415I-4R-1, 136–139 cm [Piece 12]). C. Gabbronorite with plagioclase crystals showing annealed grain boundaries with 120° triple junctions (Sample 345-U1415I-4R-1, 48–50 cm [Piece 8A]). D. Olivine gabbro with plagioclase crystals showing annealed grain boundaries and deformation twins (Sample 345-U1415I-2R-1, 2–6 cm [Piece 1]). E. Olivine gabbro with plagioclase crystals showing subgrains (Sample 345-U1415I-1R-1, 1–4 cm [Piece 1]). F. Gabbronorite showing irregular, bulging grain boundaries between plagioclase crystals and clinopyroxene, suggesting grain boundary migration and dissolution (Sample 345-U1415I-5G-1, 12–14 cm [Piece 3]).
