Figure 13. Upward-darkening sequences in Subunit IIC. A. Three upward-darkening and -fining sequences separated by fractures between core biscuits. The lower (90-99 cm) and upper (60-74 cm) sequences have thin, calcareous, silty fine sand intervals at the bases. The middle (74-86 cm) and upper sequences exhibit parallel lamination in nannofossil silty claystone. All three sequences show bioturbated intervals having Planolites and Chondrites overlain by massive, presumably intensely bioturbated, darker-colored hemipelagic/pelagic claystones (Interval 149-897C-40R-6, 60-100 cm). B. Core showing partial cut-out at the top and bottom of turbiditic sequences. The lower sequence (34-42.5 cm) shows a thin, sharp-based, silty interval, but no hemipelagic/pelagic sediment (i.e., with top cut out) as this was eroded before the overlying sequence was deposited. The upper sequence (25.5-34 cm) lacks a basal sand ("base cut-out"; Interval 149-897C-39R-5, 23-45 cm).
