Soil-geomorphic Evolution of a Boroll Catena in Southwestern Alberta1

Abstract

Abstract

The geomorphic and pedological processes that have influenced the development of a Boroll catena in south-western Alberta are examined using a combination of sedimentological and pedological techniques. Four geomorphic episodes are responsible for the sediments in the catena: the deposition of glacial till, two colluvial episodes, and a final eolian episode that deposited a thin mantle of sediment over the landscape. The vertical and lateral distribution of grain size fractions in the landscape is largely the result of these geomorphic processes. The vertical distributions of Fe and CaCO3 show some relict features from earlier phases of pedogenesis, whereas the organic C values appear to be related only to the present configuration of the landscape.
