Overview of the age, evolution, and petroleum potential of the Eagle Plain Basin, Yukon

New mapping, biostratigraphy, geochemistry, and organic petrology results have led to new insights into the structural evolution, depositional history, and resource potential of the Eagle Plain Basin. Apatite fission-track modelling resolves at least two distinct
heating-cooling cycles and suggests that sediment was sourced from the east, as well as from the south. A recently identified marine-slope setting in the west of the basin represents a new petroleum play. Advances in understanding the age and depositional history of the Eagle Plain Group derive from
new fossil localities, a new bentonite age, and detrital zircon data. Initiated in the Cenomanian, or possibly latest Albian, deposition continued until the late Maastrichtian, although post-Coniacian deposits may have been subsequently eroded, or bypassed across southern parts of the basin. New
petroleum resource appraisals include new petroleum exploration-play concepts, as well as qualitative assessments of unconventional oil and gas potential.
