Thus, several authors suggest that the accumulation of sandy deposits in a fluvially dominated, prograding
delta is the most possible sedimentary environment for the Sietini Fm.
The Higueruelas and Villar del Arzobispo Fms were deposited in a prograding
carbonate platform affected by storms with an upwards decrease in oncoid development and increase in siliciclastic discharges from continental areas.
At the eastern, along the prograding
zone of the spits of the rivers, where the waves reached up to 0.
Further, both of these spots showed similar rapidly prograding
longitudinal drifts with respect to System 3.
This dates the isolation of the ridge at the prograding
beach edge above regular tides by about the sixth century AD.
How much a beach is eroding or prograding
in any given location is due to some combination of these factors, which vary from place to place.
had suggested a prograding
upward sequence for the Patala Formation.
A high proportion of these occur in the most actively prograding
areas in conjunction with recently formed estuarine wetlands.
The formation delineates prograding
clastic wedges that were associated with the Devonian Acadian orogeny (e.
Dramatic landscape change during this period, as sea levels stabilised and coastal plains began prograding
seaward, with the decline of the Big Swamp Phase, was accompanied by important cultural changes.
At the time that Lapita designs appeared, the mid-Holocene networks were probably undergoing change firstly, due to the rapidly prograding
shoreline and advancing Sepik-Ramu floodplain (Chappell 2005), which cut off direct ties between the New Guinea highlands and the coast and, secondly, as a consequence of the Witori W-K2 volcanic eruption in New Britain that must have seriously disrupted social groups in that region (e.
During the Olympia interglacial period most of the basin was filled with sediment and then subsequently excavated during the Fraser Glaciation, except for a group of isolated banks; the southern basin was partially filled by the prograding
Fraser River Delta during the Holocene.
