Sentence examples for sheet glaciation from inspiring English sources

The nature of the regolith that existed on the shields of the Northern Hemisphere at the onset of ice sheet glaciation is poorly constrained.

Unlike inselbergs found in the tropics, the inselbergs in northern Sweden were exposed to ice sheet glaciation for long periods of the Quaternary.

Although the imprint of extensive shelf-edge ice sheet glaciation exists in the coastal landscape of western Scotland, the dominant landscape features relate to a restricted, marine-proximal mountain ice sheet with markedly different flow configurations.

The long-term evolution of the East Greenland fjord region is investigated using geomorphological and stratigraphical evidence to: (1) assess the nature of landscape modification caused by late Cenozoic ice sheet glaciation; and (2) relate patterns of glacial landscape modification to first-order (i.e. continent-margin scale) topography and geology.

There, evidence of three ice-sheet glaciations: Orting, Stuck, and Salmon Springs are found beneath deposits of the Fraser advance, and all pre-date the Brunhes-Matuyama boundary.

The Wisconsin (latest stage of Pleistocene glaciation) ice sheet was responsible for shaping the present Great Lakes system, which drains mainly eastward to the Atlantic through the St . LawrenceRiver, during its retreat.

The unique character of the region east of the Elbe is further enhanced by the fact that the ice sheets of the last glaciation coming from the north blocked the river's natural flow to the Baltic, forcing it to escape laterally around the margin of the ice toward the North Sea; the river cut a deep trench as it did so.

Much of their current geographic distribution was unavailable until ∼10,000 ybp due to the extensive ice sheets of the Wisconsin glaciation (last glacial maximum 18,000 20,000 ybp) [17].

At much longer timescales, sea level changes due to water storage in ice sheets during periods of glaciation will have major impacts on the distribution of available intertidal habitat.
