Shelf-margin architecture variability and its role in sediment-budget partitioning into deep-water areas

In Icehouse settings, there is a strong, cross-shelf accommodation drive created by high-frequency and high-amplitude eustatic sea-level changes, thus causing significant and frequently repeated transits of river mouths and deltas across the shelf. Sandy basin-floor fans created by low accommodation are predicted with either high or low sediment flux. Both medium and high accommodation can be volumetrically overwhelmed by high sediment supply, which, in turn, cause greater volumes of sediment storage on the shelf, resulting in volumetrically less significant highstand or transgressive submarine fans. However, a low supply may barely allow deltas to reach the shelf edge, causing the deep-water areas to be dominantly muddy.
