Throughout Cretaceous and Tertiary time on the North Slope, clastic debris was shed northward from the rising ancestral Brooks Range to fill the adjacent foredeep and to prograde northeasterly across the subsiding Barrow arch to form a passive margin sequence. Study of these southern source sedimentary rocks, known as the Brookian sequence, in wells and on seismic records along the Barrow arch in the National Petroleum Reserve in Alaska (NPRA) and only in wells east of NPRA shows a consistent style of deposition. This style is characterized on seismic reflection records by a distinct topset-foreset-bottomset profile that is inferred to represent a time line and thus a depositional profile.
