Lynch and Tremblay (1994) and Lynch and Giles (1996) proposed the extensional Ainslie detachment, a large low-angle extensional fault localized near the base of the Windsor Group in the western Cape Breton Highlands, detected by a layer of calc-mylonite and a stratigraphic gap within the Windsor Group.

Following Fyson (1967), Lynch and Tremblay (1994) further proposed that extensional deformation within the Maritimes Basin is not limited to the Margaree Shear Zone, but reoccurred during the late Namurian-early Westphalian with the development of a regional flat-lying extensional fault (the Ainslie Detachment) that developed within the basin fill.
