Figure F26. Photomicrographs of glass margins of lava flows showing development of tabular elongate plagioclase and plagioclase-clinopyroxene intergrowths, Hole U1347A. Note development of dark spherulitic coatings to the minerals. Depths are at top of thin section interval. A. Top of Flow 2; 174.93 mbsf (Thin Section 78; Sample 324-U1347A-13R-7, 69–72 cm). B. Top of Flow 4; 206.1 mbsf (Thin Section 93; Sample 324-U1347A-17R-2, 27–30 cm). C. Near top of the middle pillow stack of Unit XII; 263.64 mbsf (Thin Section 124; Sample 324-U1347A-23R-3, 1–4 cm). D. Near base of the lower pillow stack of Unit XIV; 291.78 mbsf (Thin Section 143; Sample 324-U1347A-26R-1, 108–111 cm). Plane-polarized light.
