Sedimentology and fossil-fuel potential of the Upper Carboniferous Barchois group, western Newfoundland
The coal-bearing Upper Carboniferous Barachois Group of western Newfoundland consists of the youngest known rocks in the St. George's Bay Lowlands. These lowlands are part of the Bay St. George Subbasin, which, in turn, is part of a network of Carboniferous depositional areas in eastern Canada....
