Abstract
Eagle Plain Basin is a relatively unexplored intermontane basin located in northern
Yukon Territory. Previous studies of the middle to Late Albian Parkin Formation and Late Albian to Early Cenomanian Fishing Branch Formation are based on broad lithostratigraphic correlations and require revision. Facies transitions, paleoflow indicators and isopach maps indicate an overall northward and westward transition to more distal depositional environments
coupled with an increase in accommodation space. New fossil evidence indicates that the units are older than previously thought which allows refinement of the paleogeography of northern Yukon and Northwest Territory during the middle Cretaceous. A relatively fine-grained shelf
margin and slope succession exposed in west-central Eagle Plain Basin indicates 200-300 m relief (not decompacted) was present between the shelf and the basin floor of the Keele Trough during the Albian. Turbidite facies indicate a very low degree of flow confinement on the slope. Newly mapped reservoir facies greatly increase the potential for hydrocarbon reservoirs in
stratigraphic or combined structural stratigraphic traps.
