Deformation of the Macumber Formation, Antigonish Basin, Nova Scotia: implications for the Ainslie Detachment

Abstract: The Antigonish Basin is one of several Carboniferous structural basins in northeastern Nova Scotia, the evolution of which have been cited as evidence for major detachment faulting within the Vis. Windsor Group of Maritime Canada. Evidence of extension in the Antigonish Basin takes the form of a major subhorizontal structure that closely follows the basin margins and has been interpreted as part of the regional Ainslie Detachment. Placed at the top of the basal Macumber Formation and reportedly characterized b… Show more

“…The stratigraphy of the Windsor Group is complicated by the plethora of formation names used in individual depocentres, but broad correlations can be made across the basin (Waldron et al, 2017;Snyder & Waldron, 2021). In Nova Scotia, the basal unit of the Windsor Group is laminated limestone of the Macumber Formation (Boehner, 1984), which laterally transitions and thickens to biohermal mounds on local palaeotopographic highs (e.g., Meguma Supergroup rocks) where it is referred to as the Gays River Formation (Giles et al, 1979;Boehner et al, 1989;Thomas et al, 2002). Basal Windsor Group carbonate strata are generally overlain by a thick succession of interlayered evaporitic, clastic, and carbonate rocks, including the Carrolls (modified from Waldron et al, 2015 andGibling et al, 2019).…”
