... of the rocks of the Canadian Shield into the Central Arctic. The Snowblind Bay Formation on Cornwallis Island has not previously been related to a source area. Thorsteinsson and Fort ier (1954) and Thorsteinsson (1958) first described the Si luro-Devonian stratigraphy of Cornwallis Island, defining the Cape...

... the Snowblind Bay Formation of Cornwallis Island. The Snowblind Bay Formation, 578 m thick, has been divided into three facies associations based on constituent lithologies, sedimentary structures and biota. The fine-grained facies association (70-220 m thick) contains less than 10% conglomerate and occurs...

Maximum and minimum reflectances were measured for the large and anisotropic bitumen fragments; random reflectances were measured for the small and isotropic fragments. Bitumen...

... to a thickness of 5,530 ft (1,686 m) reported by Thorsteinsson and Kerr (1968) . On Cornwallis, a maximum thickness of 6,450 ft (1,966 m) was measured near Read Bay (section 7), but may include 500 ft (152 m) or more of Read Bay as mapped by Thorsteinsson (1958) . At Snowblind Creek (section 6), approximately...
