Figure F51. Photomicrographs in plane-polarized light showing groundmass texture of basalt from Hole 1179D. A. Clinopyroxene bunches with plagioclase (Sample 191-1179D-10R-1 [Piece 1, 44-46 cm]) (see "Site 1179 Thin Sections"). B. Plagioclase and plumose crystallites (Sample 191-1179D-20R-4 [Piece 1C, 21-23 cm]) (see "Site 1179 Thin Sections"). C. Plagioclase clusters with magnetite and clinopyroxene (Sample 191-1179D-21R-1 [Piece 1C, 28-30 cm]) (see "Site 1179 Thin Sections"). D. Hyalopilitic texture (Sample 191-1179D-10R-1 [Piece 5B, 102-104 cm]) (see "Site 1179 Thin Sections").
