Colville Foreland Basin and Arctic Alaska Prograded Margin Tectono-Sedimentary Elements, northern Alaska and southwestern Canada Basin
Bibliographic record
Abstract
Cretaceous (post-Neocomian)–Quaternary Brookian strata of Arctic Alaska include the Colville Foreland Basin (CFB) and Arctic Alaska Prograded Margin (AAPM) Tectono-Sedimentary Elements (TSEs). The CFB TSE lies beneath the Alaska North Slope and Chukchi Sea shelf, and the AAPM TSE lies beneath the Arctic Alaska continental terrace of the Beaufort Sea shelf and slope. The CFB TSE rests on rocks ranging from pre-Mississippian sedimentary and metasedimentary rocks (Franklinian sequence) to Lower Cretaceous strata, and is present at the land surface onshore and the seafloor offshore. The AAPM TSE generally rests on Lower Cretaceous (Neocomian) sedimentary strata and is present at the seafloor. The CFB and AAPM TSEs contain oil-prone source rocks in Cretaceous and Paleogene strata, and have been charged locally by hydrocarbon migration from pre-Brookian strata. Both TSEs contain proven reservoir rocks throughout the succession. The CFB TSE ranges from oil-window to gas-window maturity. The AAPM TSE is mainly in the gas window. Known hydrocarbon accumulations in the two TSEs total more than 3.4 Bbbl of oil equivalent and yet-to-find estimates suggest an even larger volume remains undiscovered. Current exploration is focused on shallow stratigraphic traps, in which giant oil accumulations have been discovered in recent years.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
