Figure F53. Photomicrographs showing fine-grained groundmass textures of basalts from Hole 1179D. A. Subophitic texture in cross-polarized light (Sample 191-1179D-22R-5 [Piece 6B, 114-116 cm]) (see "Site 1179 Thin Sections"). B. Subophitic texture in cross-polarized light (Sample 191-1179D-12R-1 [Piece 15A, 120-122 cm]) (see "Site 1179 Thin Sections"). C. Skeletal plagioclase in plane-polarized light (Sample 191-1179D-22R-4 [Piece 4A, 80-82 cm]) (see "Site 1179 Thin Sections"). D. Lathlike plagioclase in plane-polarized light (Sample 191-1179D-22R-5 [Piece 7, 135-137 cm]) (see "Site 1179 Thin Sections").
