- •
We document a progradational shelf-margin composed of alternating forced-regressive and normal-regressive slope clinoforms.
- •
Forced-regressive clinoforms are associated with shelf-edge deltas/shorefaces.
- •
Normal-regressive clinoforms are truncated by large slump scars.
- •
Sandy turbidites occur associated with both rising and falling relative sea levels.
- •
Large mass-transport deposits formed preferentially during the onset of base-level falls following a period of positive accommodation at the shelf margin.
