Geology comments: "Throughout much if not all of the Archipelago, the boundary between the Silurian and Devonian Systems, as presently defined, is transitional and not represented by a hiatus. Moreover, the S-D boundary is represented in contrasting facies: graptolitic, shelly, redbeds, and flysch deposits. The graptolitic rocks occur in outer parts of the Franklinian Geosyncline, and are exposed on Melville, Bathurst, Cornwallis, Baillie Hamilton, Devon and Ellesmere Islands. The shelly facies occurs in inner parts of the F.G. and on the adjoining Arctic Platform, and is exposed on Victoria, Stefansson, Cornwallis, Devon and Ellesmere Islands. The redbeds crop out in the environs of a prominent cratonic uplift (Boothia Uplift) on Cornwallis and Prince of Wales Islands. Outcrops of the flysch deposits are confined to northern Ellesmere Island."
