Revised Stratigraphy of the Hunting Formation (Proterozoic), Somerset Island, Northwest Territories
In a revision of the stratigraphy of the Hunting Formation three members are recognised in the vicinity of the lower reaches of the Hunting River, northwestern Somerset Island. Member 1 rests conformably upon the Proterozoic Aston Formation and consists of sandstone, sandy dolostone, and dolostone;...
