EAS 324 - The Quaternary of Alberta
The modern land surface
Recent sedimentary deposits overprinted on an eroding complex of predominantly late
quaternary glacial sediments deposited during Alberta's last glaciation
Sediments overlying the bedrock unconformity
The Paleogene and Neogene fluvial sediments, preglacial sands and gravels and any
glacial sediments deposited prior to the last glaciation
Where is the thickest sediment in Alberta
The northwest corner and the Wiau channel
Distribution of sand and gravel follows
The distribution of buried valleys
Alberta is mostly a what kind of landscape
Primarly a fluvial landscape
Fluvial erosion
The incision of the landscape by rivers
Excess of 2km of erosive material in the WCSB is a result of
Lateral planation
As uplift decreased in Alberta
migration of sand and gravel occurred eastward along the high gradient from the rocky
mountains
Within the interior plains, sand and gravels get deposited
