Figure F19. Core images of Sections (A) 324-U1347A-17R-2 (Unit IX) and (B) 13R-7 (Unit V), (C) thin section scan, and (D, E, F, G) photomicrographs (plane-polarized light) of chilled lava/sediment contacts within the glassy upper crust of massive submarine flow in Unit V, Hole U1347A. Thin section scan location of C (made from bottom of billet on working half of core and so is not identical to image in A) is indicated by the red box in A. Red boxes in C indicate photomicrograph locations. Dashed yellow lines in D, E, and G outline part of the fine-grained sediment/glass contact. Height of field of view of D, E, and G is ~6 mm (2.5x). Height of field of view of F is ~1 mm (20x).
