“…and Permian age. Armstrong, Mamet, and Dutro (1970) and Mamet and Armstrong (1972) reported the Lisburne Group within the area of this study to be of Late Mississippian to Middle Pennsylvanian (Atokan) age. The age assignments are based on microfossil assemblages.…”

“…Brosge, Dutro, Mangus, and Reiser (1962) defined the northward transgressive nature of the Lisburne Group carbonate rocks in the central and eastern Brooks Range. These studies were continued by Armstrong, Mamet, and Dutro (1970), Mamet and Armstrong (1972), and Armstrong (1974), who also delineated the Sadlerochit high that appears in part to parallel the present-day Sadlerochit and Shublik Mountains.

“…Dr. B. L. Mamet identified the microfossils, and his microfossil zones are the basis for the regional stratigraphic correlations in this study. Detailed documentation of the microfossil zones used in the stratigraphic section of this report can be found in Armstrong, Mamet, and Dutro (1970) and Mamet and Armstrong (1972).…”

Depositional sequence mapping has been used to analyse the late Devonian to Recent geologic evolution and hydrocarbon habitat of north Alaska and northwest Canada. Eight depositional megasequences have been identified, each of which records a discrete, major phase of basin evolution. The three oldest megasequences are named the Ellesmerian and reflect deposition on a subsiding fold belt terrane. We name thc subsequent two megasequences of early Jurassic to Aptian age, the Beaufortian. They record a 100 Ma period of extension during which a Jurassic failed rift episode was followed by onset of the successful rift episode in the Hauterivian. This extension led to the opening of the oceanic Canada Basin. The final three megasequences record geographically distinct pulses of Brookian orogenesis.The major proven hydrocarbon habitat occurs on the Barrow Arch of north Alaska. This is a volumetrically large, but greatly restricted, hydrocarbon province, which developed as a result of constructive interference between Beaufortian rift and Brookian orogenic tectonics. Two other, relatively minor, hydrocarbon provinces have also been discovered. They are the Mackenzie Delta and Kugmallit Trough provinces of northwest Canada, which developed in passively subsided basins, located just beyond the influencc of Brookian orogenic uplift.
