Models of aggradation versus progradation
in the Himalayan foreland.
(1996) concluded that cyclicity could be explained due to frequent progradation
and retreat of what was basically a straight, tide-influenced shoreline onto a storm-dominated marine shelf.
of this Top End low-energy coast is ongoing today in the context of a climate characterised by two major and clearly delineated seasons--an extended seven-month dry season from May to November, and a wet season from December to April featuring severe storms and cyclones that impact upon the coast.
In Argentina, the progradation
of the Parana River Delta sets up a large sequence of change from sediment bars, continuously depositing at the shoreline, to mature islands located upstream, formed 700-900 years ago (Iriondo & Scota, 1979).
Catherines Island records episodes of deposition interrupted by erosion spanning more than 3000 years of progradation
(based on archaeological data).
Hove, (1992) offers a possible explanation for these anomalies, according to him, the Ea sequence (or generally, Offshore wells) show an upward change from sand dominated lowstand deposits intercalated with transgressive and highstand shales towards thicker and more sand prune highstand and transgressive deposits interrupted by thinner lowstand deposits (reflecting overall progradation
across the depobelt),.
Durant la periode interglaciaire d'Olympia, la plus grande partie du bassin a ete rempli de sediments, lesquels ont par la suite ete excaves durant la glaciation de Fraser, sauf un groupe de bancs isoles; la partie sud du bassin a ete partiellement remplie par progradation
du delta de la riviere Fraser a l'Holocene.
Diversion of the Peneus River has led to cycles of delta progradation
and retrogradatiin that have both buried and eroded archaeological sites.
It is likely that during Raikkula time the zone of dolomitization gradually migrated southwestwards in accordance with progressive shallowing and progradation
of the carbonate shelf, especially in the second half of the time.
of the shoreline added an additional 49 beach ridges over the next 3,500 years.
The predominance of gravelly deposits in the base of the Sharon Formation, and the coarsening-upward sequence, imply progradation
under stable or rising sea level conditions.
Prolific production of grainy nearshore carbonate sediment on the flanks of paleohighs initiated progradation
of shallow-water strata.
