The structures involve sedimentary sequences ranging from Devonian to Tertiary in age. The interpretation shows an east-verging allochthonous wedge with a lower detachment at the base of the Mississippian sequence and an upper detachment within the Upper Cretaceous Belly River Formation. Backthrusts branch from the upper detachment in a foreland directed sequence. Detachments occur at various levels resulting in separate duplexes in individual stratigraphic units. The wedge comprises four structural packages separated by the upper, lower and top-Mississippian detachments. Each package develops and varies geometrically along strike and affects the overlying structures. Average shortening is 52% and 38% respectively at the Cretaceous and Mississippian levels and 17% in the hangingwall of the upper detachment. Faults that cut across package boundaries are interpreted as out-of-sequence.xii, 104 leaves : ill. & folded maps ; 30 cm.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
