Figure 13. Example of irregular vertical variation within individual sequences. An upper, normally graded laminated sequence is interpreted as a muddy turbidite, with parallel-laminated sandy siltstone and silty claystone at its base (1B), grading upward to silty claystone (2B) and light-colored bioturbated claystone with silt (3B). Lower sequence shows cross-stratified and parallel-laminated, mixed biogenic and terrigenous sandstone (1A), with a sharp base and top intercalated between structureless, light-colored nannofossil clay (3) and darker silty clay (4); 1A is interpreted as a contourite (Subunit IIB, Interval 149-898A-33X-3, 59-84 cm).
