These units have been thrust faulted and have undergone multiple phases of folding. Four deformational events are recognized. D1 develops NNW-SSE trending F1 folds and associated thrusts in Ordovician and Silurian strata. D1 is correlative with movement on the Boothia Uplift (Late Silurian–Early Devonian). D2 develops F2 folds and west-directed thrust faults that are co-axial with F1 but affect late Middle Devonian and older strata. D3 exhibits east-west trending F3 folds and is correlated with the Ellesmerian Orogeny (Late Devonian to Early Carboniferous). F3 folds re-fold F1/F2 folds creating interference patterns at a variety of scales. D4 is defined by northwest-southeast trending F4 folds. F4 folds overprint F1/F2 folds, and are unaffected when axial surfaces of F3 are crossed. D4 may possibly be associated with the Paleogene Eurekan Orogeny. Hydrothermal dolomite and Zn-Pb mineralization are strongly controlled by pre-exisiting structures. Specifically, they correlate most commonly with thrusts (preferentially east-directed thrusts) and along the hinge surface traces of regional F3 folds.

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.
