The Franklinian Orogeny, in the northwestern Canada (Plafker & Berg, ... In the northern part of the Devonian basin system, sedimentation was influenced by several periods of compression phases that ended with pre-Tournaisian folding and thrusting. Abundant red beds, molasse, and continental evaporites were deposited in basins in the …

The formation of Franklinian basin probably started in the Pre-Cambrian stretching from Arctic Canada to North Greenland. It was probably initiated by the break-up of supercontinent Rodinia about 750 Ma. ... At the initial stage, the basin experienced transgression and regression events and sedimentation took place in a low-energy …

Our models suggest that the cratonic areas were buried beneath a several km-thick succession of Franklinian Basin deposits. During the Ellesmerian Orogeny, …

Franklinian Basin sedimentation was brought to an end by uplift at the end of the Devonian. ... Sediments were shed from the Nevadaplano and intervening Sierra Nevada region into these basins. Eocene sedimentation is also recorded in the Tyee basin of Oregon and Nanimo basin of Washington-British Columbia.

Abstract. The Franklinian Basin extends from the Canadian Arctic Islands to eastern North Greenland, a distance of approximately 2000 km. In the North Greenland …

The Devonian and older Franklinian megasequence constitutes a transition from passive margin to foreland-basin sedimentation, culminating with significant fold-and-thrust belt development (Sherwood, 1994). ... dominantly carbonate shelf facies, of the Franklinian Basin in the Canadian Arctic Islands (Fox, 1985; ...

Formation is the uppermost succession of Ellesmerian Orogen foreland basin sedimentation in the Franklinian Basin. Detrital zircon from four samples yield U–Pb age populations of 370–450, 470–750, 930–2100, and 2300–3200 Ma.

The Greenland part of the Franklinian Basin was mapped systematically by the Geological Survey of Greenland in the period 1978–85. Throughout the Early Palaeozoic, the basin was divided into a southern shelf and slope and a northern deep-water trough. ... Sedimentation was brought to an end by the late Devonian – early Carboniferous ...

Franklinian Basin sediments derived from Pearya contain numerous grains in the 480–455 Ma interval (Hadlari et al., ... 2016), that is ∼50 m.y. after northerly derived sedimentation in the Sverdrup Basin began. An alternative model with a single arc would require a landward migration of arc magmatism and the drainage divide, which would ...

During at least two periods in the basin history, sedimentation overstepped fault zones under a regime of thermal subsidence to blanket much of the region. ... The Devonian and older Franklinian sequence consists of sedimentary and metasedimentary rocks deposited on the Arctic passive margin of Laurentia and in a Devonian foreland basin, and ...
