An Intensive Local Application of Lensen's Isallo Stress Theory to the Sturgeon Lake South Area of Alberta

Paul H. Lu, Adrian E. Scheidegger

ABSTRACT

Isallo Stress maps of an area 24 by 24 miles in Central Alberta, Canada, were drawn to test Lensen's theory. Two types of maps were drawn: one without and one with the a priori assumption of a principal horizontal stress (PHS) direction. It is shown that in either case, regions with incipient transcurrent faulting are preponderant over all others, a result which is in conformity with results from recent seismological investigations. The faulting patterns found are in full conformity with those that could be produced by the tectonic stresses which created the Rocky Mountains.
