Figure F7. A. Photograph of normally graded sequences (interval 324-U1346A-4R-2, 50–59 cm). Arrows = fining upward. B. Smear slide image of fine clayey material in graded sequence. Volcanic glass shard is circled in red. Plane-polarized light. C. Thin section of coarse volcanic sandstone (interval 324-U1346A-4R-2, 127–131 cm). D. Bioturbated horizon (interval 324-U1346A-4R-2, 107–108 cm) indicating period of quiescence before next depositional event. E. Flame structures (interval 324-U1346A-4R-2, 122–124 cm) indicating sediment deposition in turbulent flow conditions.
