Subsurface mapping of Ellesmerian onlaps: Testing the opening of the Arctic Canada Basin
Bibliographic record
Abstract
Since the advent of plate tectonics in the mid-1960's the mechanism for formation of the majority of the world's ocean basins has been solved. However, there are still several remaining tectonic conundrums, such as the origin of the Arctic Canada Basin. The most widely accepted tectonic hypothesis proposes a rotational opening of the basin after rifting along the Northern Alaskan-Canadian Arctic margins.;Subsurface mapping the Ellesmerian strata of Northern Alaska onlapping onto the Barrow Arch, a long-lived basement high, was carried out and then compared with mapped strata on Prince Patrick Island, Canada, to see if they aligned. These mapped onlaps appear to show a match between Northern Alaska and the Canadian Arctic, if Northern Alaska is rotated back clockwise by 60° about a Euler pole located at 68.9°N, 229°W. Along with recent gravity and magnetic anomaly data, all this new evidence would appear to be consistent with a rotational opening.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
