Record #195016:

End moraine construction by incremental till deposition, Southern Ontario, Canada / Nick Eyles, and 3 others.

Title: End moraine construction by incremental till deposition, Southern Ontario, Canada / Nick Eyles, and 3 others.
Author(s): Eyles, Nick.
Date: 2011.
In: Boreas. (2011.), Vol. 40(1) (2011)
Abstract: Presents subsurface sedimentological data from prominent end moraine (Trafalgar Moraine), aiming to contribute to understanding of "soft beds" and formation of associated landforms. Analyzes water well stratigraphic data, drilled sediment cores, downhole gamma-ray logs and exposures in deep test pits. Shows that ramp-like moraine, composed of silt-rich Wildfield Till, is built of superposed beds up to seven metres thick. Proposes model in which repeated incremental deposition of fine-grained debris formed by mixing of lake sediments and shale moves towards margin as deformable bed beneath ice-sheet margin. Suggests that ~0.81 km³ till was moved/deposited in brief readvance of Ontario lobe around 13 300 ¹⁴C a BP. Discusses wider applicability to region's ramp-like till-cored moraines.
