Figure F11. (A) Core photograph (wet) and (B) sketched interpretation showing relationships between lithologic Units 7, 8, and 9 (interval 330-U1377B-4R-5W, 1–34 cm). Lithologic Unit 9 appears to have intruded into breccia (Unit 7) to form a mixed zone (Unit 8), the intrusive matrix of which is glassy in its upper part. Part of the space between clasts was originally empty and is now filled with carbonate. Units highlighted in B are colored according to lithology, as in the stratigraphic column in Figure F8.
