Figure 9. Slump structures in Subunit IIB. A. Deformed zone probably produced by slumping. The deformed claystone interval (1) is overlain by a deformed clayey siltstone (2), which is truncated by a nannofossil claystone with Chondrites burrows; Interval 149-899B-5R-3, 30-61 cm. B. Small slump fold at the base of an upward-darkening sequence; Interval 149-899B-7R-4, 85-95 cm. C. Large slump fold that has inverted a sandy basal interval of attribute: (1) silty sand base; (2) bioturbated nannofossil claystone repeated by fold (lower interval is the right way up); (3) nannofossil claystone in core of slump fold (Interval 149-899B-8R-3, 93-139 cm).
