Abstract

North- to northwest-directed crustal shortening across the western Quetico subprovince and its boundary regions produced a complex deformation sequence within the Quetico belt and resulted in concentrated zones of dextral ductile shear in the boundary regions within the adjacent greenstone-granite terranes. In this paper, data on the regional deformation features and their geometries is introduced and the history of generation of these features is discussed. The deformation sequence is attributed to differential partitioning of shortening and shear strains during dextral transpression associated with oblique convergence and accretion along the southern margin of the Superior Province. -from Authors
