Figure F9. Core photograph of sharp-based two-part sand bed with lower clean sand division (64–59 cm) with shell fragments concentrated at the top and no bioturbation and upper silty sand division (59–54 cm) with low-angle laminations, clay, and no bioturbation (interval 313-M0028A-80R-2, 43–67 cm). Above 54 cm is muddy and bioturbated fine sand. These two-part beds are interpreted as combined flow deposits under the influence of geostrophic (lower division) and storm wave (upper division) generated currents.
