Figure 5. Sequence model of deposition on shelf and slope through a glacial cycle (adapted from
Larter and Barker, 1989, 1991b). Unsorted till is deposited on the slope (foresets) during glacial
maxima and on the shelf (topsets) during retreat. Pelagic or hemipelagic sediment is deposited on
the slope and rise during interglacials. With re-advance, some or all shelf topsets may be eroded.
