Figure 11. Upward-darkening sequence in Subunit IIB (Interval 149-900A-42R-6, 110-123 cm), consisting of a basal, slightly bioturbated parallel-laminated foraminifer-rich sandstone (1) passing upward into laminated sandy siltstone (2) and capped by darker moderately bioturbated claystone (3). The sequence is interpreted as a turbidite.
