Ellesmerian fold-and-thrust belt (northeast Ellesmere Island, Nunavut) and its Eurekan overprint
Bibliographic record
Abstract
Between the Lake Hazen Fault Zone and Nares Strait on northeast Ellesmere Island, a several kilometre thick succession of deep-water and shelf deposits of the early Paleozoic Franklinian Basin was affected by Late Devonian to Early Carboniferous Ellesmerian deformation (D1). Dominant structures were long anticlines and synclines, and detachment faults above a major décollement at the base of the Franklinian Basin. In the Early Tertiary, sinistral strike-slip tectonics (D2) affected the Franklinian deposits and Paleocene basins parallel to Nares Strait. In the Eocene, all structures, as well as the D2-strike-slip faults, were affected or reactivated by Eurekan deformation (D3). Crustal shortening took place along the Ellesmerian décollement and was dominated by thrusting. On the surface, the Eurekan structures are characterized by major, hundreds-of-kilometres long, distinct thrust zones with subordinate, thrust-related fold structures (F3), and are interpreted as large-scale splay thrusts ramping up from the basal décollement. In the areas between those thrust zones, already folded during the Ellesmerian deformation, no evidence for Eurekan overprint was found.

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.
