Figure F27. Photomicrographs of olivine pseudomorphs, Hole U1347A. A. Pseudomorph located in a spherulitic portion near the margin of Flow 2 and replaced by clays but still showing skeletal morphology; 174.21 mbsf (Thin Section 75; Sample 324-U1347A-13R-6, 139–142 cm). B, C, D. Flow 2; 187.71 mbsf. In B, pseudomorphs are replaced by clays but still show altered glass inclusions (dark circular spots). In C, they are intergrown with euhedral plagioclase, partly skeletal, and contain plagioclase in elliptical interior inclusion. In D, a broken crystal is replaced by both clay and calcite (white) (Thin Section 85; Sample 324-U1347A-15R-2, 24–26 cm). E. Relict fresh olivine with single spinel grain. Top of Flow 2; 174.93 mbsf (Thin Section 78; Sample 324-U1347A-13R-7, 69–72 cm). Plane-polarized light.
