Using GIS as a method of identifying controls on the distribution of sediment in the Selwyn Mountains, Yukon Territory
The following paper outlines a method of identifying controls on the distribution of postglacial alpine sediments in the Selwyn Mountains using a Geographic Information System (GIS) as a vehicle to analyze surficial geology maps, bedrock geology maps, and topographical data.
Postglacial alpine sediments in this region include talus, rock glaciers, alluvial fans and Neoglacial till and the spatial distribution of these sediments is controlled by factors such as lithological properties and site characteristics which in turn influence weathering and erosion. As a result, the sediment distribution may give clues about the bedrock weathering and site conditions. The method of cross tabulation is a powerful tool that can provide insight into the spatial patterns of landforms, and processes such as sediment accumulation and landscape denudation. It allows an examination of the distribution of bedrock and surficial geology units with respect to each other and to other map variables such as elevation, slope and aspect. The analysis of the spatial distribution of sediment and the calculation of rates of landscape denudation for different bedrock units then require the use of a G.I.S.
Preliminary results suggest that rates of denudation are controlled by a number of factors including bedrock type and site conditions such as elevation and aspect.
