| The Paskapoo Formation, of Paleocene age, is an important, but poorly understood groundwater aquifer in western Alberta, and is now becoming recognized as a shallow-gas reservoir. Because the Paleocene rocks represent the bedrock at surface over their area of occurrence, and have not previously been a major hydrocarbon target, there has been little study of outcrop or subsurface data. This report briefly summarizes outcrop fieldwork, primarily detailed measured sections, in the Bow River corridor, in an east-west transect, bothwithin and west of the city of Calgary, where Porcupine Hills-Paskapoo rocks are intermittently exposed. The material is presented as 15 standard measured sections, with text descriptions of units, and measured paleocurrent data, which approximate a continuous succession of the strata represented in this region. Two main facies are present: a) thick, multistoried fluvial channel sandstones with erosive bases, and b) pedogenically altered siltstones with thin sandstone interbeds and calcrete horizons. This report complements two other Open Files on outcrop sections of the Paskapoo Formation: one on the Red Deer River (GSC OF 5535), and the other on drillcore sections of Paskapoo rocks in central Alberta (GSC OF 5537). |
