Stratigraphic range: Upper Triassic
Faulted continental redbeds of the Blomidon Formation, Minas Basin North Shore, Nova Scotia.
|Unit of||Newark Supergroup|
|Underlies||North Mountain Basalt|
|Named for||Cape Blomidon|
|Named by||Klein, 1962|
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 ( ) and Paddy Island ( ).
