Figure F15. Thick massive sand bed in Subunit IB. A. Coarse sand from an ~10 m thick bed (interval 301-U1301C-11H-6, 110–120 cm). B. Granule layer within Subunit IB (interval 301-U1301C-13H-CC, 5–10 cm). C. Washed granules from the same interval as in B. The granules consist of subrounded grains of green metamorphic grains (possibly amphibolite or serpentinite), white felsic volcanics, calcareous sandstone, and shallow-water shell fragments in a matrix of soupy clay (interval 301-U1301C-13H-CC, 9–11 cm).
