Figure 14. Calcareous sandstone sequence near the base of Subunit IIB (Interval 149-900A-77R-CC, 1-28 cm), showing planar lamination (1) at the base, faint cross-lamination in the lower half (2), and discontinuous to continuous, wavy lamination at the top (3). This sequence is interpreted as a turbidite, possibly deposited in a lobe-fringe setting.
