Title: Lineaments in Avonlea Area, Saskatchewan

Author(s): W. O. Kupsch (2), J. Wild (2)

Abstract:

Linear features revealed by air-photo mosaics of the Avonlea area are due to topographic relief, stream adjustments, alignment of elongate closed basins, vegetation, and soil-moisture differences. They occur in two sets parallel with known faults and some appear to coincide with faults mapped at the surface. They are therefore regarded as lineaments, which are the surface expression of faults.

The fault pattern, the position and great length of some faults, and the location of the epicenter of a very strong earthquake are advanced as arguments for a tectonic origin of the faulting. Minor faulting due to the removal of Middle Devonian salt by solution, may have taken place after the deposition of the salt. Large faults of tectonic origin, which appear to be responsible for the Missouri Coteau, are probably basement faults along which recurrent movement has taken place.

Fault traps of hydrocarbons in pre-Middle Devonian units are possible, although the apparent displacement of older strata may not be as much as that in younger rocks.
