Fourth-order sequences 3 through 6 can be seen. Each fourth-order sequence begins with a transgressive facies tract, followed by an early regressive facies tract, and then a late regressive facies tract marked here, in the coastal plain, by progradation of fluvial sandstone sheet complexes. These are, in turn, overlain by flooding surfaces. Sequence boundaries are not unconformities but mark times of maximum regression. Incised fifth-order sequence boundary placing nonmarine gravels on marine deposits.
Sediment flux off of the uplifted moutain block is shown as q s .
Ribbon channel complexes in the alluvial plain sections are only diagrammatic. See original paper for discussion.
