Structural Geology of the Moose Mountain Area, Alberta
Abstract
The surface geology of the Moose Mountain area provides excellent illustrations of type structures and fundamental processes in foothills geology. The area consists of a series of fault plates separated by major sole thrusts.
In one instance the upper and lower boundary sole thrusts converge to form a wedge-shaped fault plate, a typical foothills structure. Study of the junction relationships indicates the lower or more easterly sole thrust was formed, and probably folded, before the upper or more westerly sole thrust developed.
All thrusts eventually terminate laterally or vertically. Lateral die-out is illustrated in several cases where it is apparently accomplished by transfer of motion to adjacent faults. Evidence of vertical die-out is provided by the Turner Valley sole fault where motion is dissipated upward in a crumpled zone along the eastern edge of the Foothills.
