AbstractThe Paleozoic fold belt of Atlantic Canada forms the northeastern part of the Appalachian Mountains. Within this fold belt, the Windsor Group includes the only marine rocks of Late Paleozoic age in southeastern Canada. The Windsor Group evaporites, which are preserved on land in outliers or as part of the northeastern trending basin beneath the Gulf of St. Lawrence, form part of a much larger depositional area, the Magdalen Basin. Based on present structural trends, the Magdalen Basin has been divided into a number of subbasins. The Cumberland subbasin is one of these. The Cumberland subbasin contains thick deposits of Upper Paleozoic rocks. Adjustments within the basement and uplift of the Cobequid basement block to the south, have folded the Carboniferous rocks in the subbasin into the east-northeast trending, salt-cored Malagash and Minudie anticlines and a few local structures. Massive salt accumulations occur as flow structures that are generally overturned to the north. The salt migration is considered to be the result of halokinesis and halotectonism associated with the Maritime Disturbance.
