The stratigraphy and sedimentology of the Cinq Isles formation, Fortune Bay, Newfoundland
The Cinq Isles Formation consists of up to 1500 feet of limestones, sandstones, shales and conglomerates, well exposed around the shores of Fortune Bay, southern Newfoundland. -- The succession unconformably overlies the Simmons Brook batholith towards the southeast and Cambrian shales toward the so...
