Figure F275. Band of granular assemblage (Thin Section 39; Sample 312-1256D-198R-1, 45–49 cm; 1369.46 mbsf). A. Fine-grained basalt (upper half) with very fine grained clinopyroxene + plagioclase granular assemblage (lower half) (plane-polarized light; field of view [FOV] = 4. 5 mm). B. Tiny clinopyroxene-plagioclase granular assemblage (plane-polarized light; FOV = 0.6 mm). C. Plagioclase partially replaced at rim by secondary plagioclase containing tiny fluid inclusions (plane-polarized light; FOV = 0.6 mm). Small granular clinopyroxene can also be seen.
