Continental marine transition in the Devonian of Prince of Wales Island, Northwest Territories
In eastern Prince of Wales Island the Peel Sound Formation is subdivided into upper and lower members on the basis of lithology. The upper member comprises five laterally equivalent north–south facies belts which are in westward order:1) Conglomerate Facies: cobble and boulder conglomerates deposite...
