Figure F8. Core photograph of a 40 cm thick sharp-based, normally graded bed that coarsens down from poorly sorted coarse sand at the top to gravely sand at the base (interval 313-M0029A-79R-2, 50–92 cm). See also numerous gastropods, bivalves, and shell fragments. Deposits are part of a larger package of sediment interpreted as sediment gravity flow of coarse material into deep quiet waters possibly shed from upslope rollover positions during periods of relative sea level lowering.
