Eagle Foreland Basin Tectono-Sedimentary Element, Yukon Territory, Northwest Canada

摘要: Abstract Eagle Foreland Basin Tectono-Sedimentary Element (TSE) comprises two separate parts: a larger rectilinear sub-basin of Cretaceous age (Eagle Plain) and smaller fault-bounded mid-Cretaceous to Paleogene (Bonnet Plume) in the southeast, separated from Plain by an inlier Ogilvie Platform TSE. Faulted remnants NW Canada Riftogenic TSE are locally preserved beneath northern parts sub-basin. initiated as Cordilleran foredeep was incorporated into orogen during Late deformation. It preserves dominantly marine clastic strata >2500 m thick, with thickest preservation northwest. Thermal maturity data suggest that 2000 3000 deposits were removed erosion. Petroleum potential exists, principal active sources lying within subjacent successions. is early-mature mature basin, oil gas prone deeper basin younger units. Bonnet Plume sub-basin, known for its coal-bearing strata, largely unexplored. contains non-marine marginal considered be marginally gas-prone basin.
