Regional structural reconnaissance of the southwestern Grenville Province using remotely sensed imagery

Abstract

Recent reconnaissance mapping in the western Grenville Province of Ontario by the Geological Survey of Canada has led to the delineation of discrete lithotectonic domains characterized by different structural styles, lithologies, metamorphic grade and geophysical signatures. This paper investigates the use of satelliteborne remotely sensed data (Landsat MSS, TM, SEASAT-SAR) for the purpose of delineating structural domains in the Grenville Province of Ontario and western Quebec. Image prints at a scale of 1:250 000 were visually interpreted for ductile (bedding, foliation, folds, shears), brittle (fractures, faults) and glacial features. Possible structural domains were delineated from the interpreted ductile features. -from Authors
