Canadian Arctic Prograded Margin Tectono-Sedimentary Element, SE Canada Basin
Bibliographic record
Abstract
The Canadian Arctic Prograded Margin Tectono-Stratigraphic Element (TSE) is located on the continental shelf and slope, which lie to the NW of the Canadian Arctic Archipelago. The TSE comprises a post-rift succession deposited on the eastern margin of the Amerasia Basin, and the strata range in age from Late Cretaceous to Pleistocene. Over much of the TSE, a major unconformity marks the base of the succession, and the underlying strata vary from Jurassic to Lower Cretaceous strata of the Canadian Arctic Rift Margin TSE to older Upper Paleozoic–Triassic strata of the Sverdrup Basin Composite Tectono-Sedimentary Element. Sparse reflection and refraction seismic data indicate that the succession can be more than 10 km thick. The TSE is divided into three structural domains with deformation increasing to the NE. The Southern Domain is extensional and is characterized by listric growth faults with rollover anticlines and tilted fault blocks. The pre-Oligocene portion of the Central Domain is deformed by broad folds with extensional faults in the younger strata. The pre-Oligocene succession in the Northern Domain is likely to be strongly folded and cut by thrust faults of the Eurekan Orogeny with extrusive and intrusive igneous rocks occurring in the Upper Cretaceous strata. Petroleum source rocks, as well as abundant reservoir and seal strata, occur throughout the TSE, indicating good potential for the presence of petroleum resources. The remote and environmentally sensitive location of the TSE, however, makes it likely that it will never be a target for petroleum exploration.

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.
