| 189.180 | 0.00 | 378.36 | 5 | Muddy sandstones and mudstones (minor diamictites and conglomerates) | Sequence Motif A down to 329.96 mbsf, Sequence Motif B below | Decrease in coarse sediment supply, onset of glacial advance/retreat cycles, period of rapid subsidence from 0-157.22 mbsf |
| 479.180 | 378.36 | 580.00 | 4 | Clean sandstones (minor conglomerates) | Sequence Motif B down to 480.27 mbsf, no sequences recognisable below | Slowing of subsidence, marine shelf environment established and maintained by coarse sediment supply |
| 684.885 | 580.00 | 789.77 | 3 | Muddly sandstones (minor conglomerates, mudrock-bearing interval near base) | No sequences recognisable | Marine flooding at base, relatively deep environment (probably shelfal) during initial rift subsidence, recovery with time due to increased sediment supply |
