Figure F30. Photomicrographs of melt inclusions in a single large plagioclase glomerocryst, itself occurring in volcanic glass, Hole U1347A. Top of Flow 4; 206.10 mbsf (top of the thin section interval) (Thin Section 93; Sample 324-U1347A-17R-2, 27–30 cm). A. Distribution of pale brown glass inclusions in glomerocryst. Plane-polarized light. B. Same view as A, but in cross-polarized light to show the full aggregate of crystals. C. Detail of the central portion of the glomerocryst, showing crystal-parallel and crystal-edge glass inclusions. D. Same as C, but in reflected light, to show polished surfaces of unaltered glass inclusions.
