The Blomidon Formation is a unit of Upper Triassic (Norian–Rhaetian) sedimentary rocks, which outcrops in Nova Scotia. At outcrop they reach a maximum thickness of 365 m, but up to 1168 m has been proven from well data and a thickness of up to 2500 m has been inferred from seismic reflection data. It overlies the mainly Carnian Wolfville Formation and underlies the North Mountain Basalt. The type section is exposed between Cape Blomidon (45°17′43″N 64°19′55″W / 45.29528°N 64.33194°W) and Paddy Island (45°11′51″N 64°21′34″W / 45.197372°N 64.359411°W).
