Figure F25. Typical mineral assemblages, abundances, and groundmass textures within basalts from Hole U1301B. A, B. Spherultic, hyalophitic groundmass (Sample 301-U1301B-26R-1 [Piece 7, 41–43 cm]) (field of view [FOV] = 1.4 mm); (A) plane-polarized light, (B) cross-polarized light. C, D. Intersertal, seriate texture (Sample 301-U1301B-32R-2 [Piece 2, 123–125 cm]) (FOV = 5.5 mm); (C) plane-polarized light, (D) cross-polarized light. E. Pilotaxitic groundmass plagioclase (Sample 301-U1301B-16R-1 [Piece 2, 8–10 cm]); plane-polarized light (FOV = 5.5 mm). F. Intergranular fine-grained massive basalt (Sample 301-U1301B-18R-4 [Piece 1, 17–19 cm]); plane-polarized light (FOV = 5.5 mm).
