Carbonate deposition dominated the Franklinian miogeocline from Late Cambrian until earliest Middle Devonian. Following a transgression in early Eifelian (within the costatus-costatus conodont Zone), quartzose clastics replaced carbonates as the dominant sediment type and, from that time until Early Carboniferous, clastic sedimentation was widespread across the Franklinian miogeocline. During this interval an enormous clastic wedge prograded southwestward, heralding the advance of Ellesmerian deformation.
Middle-Upper Devonian clastic sediments are widely preserved and are most widespread in the western Arctic, where they occur over much of Bathurst, Melville, Prince Patrick and Banks islands (Fig. 10.1). In the eastern Arctic the deposits...

Geology of the Innuitian Orogen and Arctic Platform of Canada and Greenland
Fourteen chapters discuss regional stratigraphy by time intervals from Precambrian to Quaternary, while other chapters describe the geography, geomorphology, tectonics, geophysical characteristics, and resources of the region. A summary chapter includes geologic maps, structural cross-sections, a geotectonic correlation chart, a gravity map, and a location map for exploration wells in the Arctic Islands and northern Greenland. A wealth of additional information is contained on the nine accompanying plates.
