Ice-flow history and drift prospecting in the Committee Bay belt, central Nunavut: results from the Targeted Geoscience Initiative
Bibliographic record
Abstract
Mapping of ice-flow indicators in the Committee Bay supracrustal belt (NTS 56 K, 56 J/9 to /16, 56-O/1 to /8, and 56 P) provides new evidence for a complicated ice-movement chronology during the Late Wisconsinan. Three main phases of ice movement have been identified at the regional scale. The oldest is northerly and is found throughout most of the area. This was followed early in the deglaciation sequence by northeastward flow in the eastern part of the area and northwesterly flow in the western part. Finally, there is a north-northwesterly flow south of the Chantrey moraines, associated with ice flow from the Keewatin Ice Divide. Results from drift-prospecting studies indicate that till geochemistry reflects a clear northerly direction of glacial transport. Most of the known gold showings are recognized in the gold-grain counts and/or the gold values in the till matrix, but at least two previously unknown, potentially gold-rich domains have been identified.

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.
