Figure F7. Thin section photomicrographs of basalt, Site U1332. Left image = plane-polarized light, right image = cross-polarized light. A. Very fine grained sparsely plagioclase phyric basalt (fresh chilled margin = subhedral clinopyroxene, lath plagioclases, and glass in groundmass) (Sample 320-U1332A-18X-CC, 12–16 cm). B. Fine-grained plagioclase phyric basalt (calcite vein and highly altered groundmass) (Sample 320-U1332A-18X-CC, 16–19 cm).
