Sedimentology, stratigraphy, and U-Pb detrital zircon geochronology of the Mesoproterozoic Husky Creek Formation, Coppermine River Group, Nunavut, Canada
Bibliographic record
Abstract
The Husky Creek Formation (part of the Coppermine River Group, western Nunavut, Canada) is a <1.23-billion-year-old siliciclastic sedimentary unit that represents the uppermost portion of the Sequence A stratigraphic subdivision – a package of Proterozoic volcanic and sedimentary rocks correlative across the Canadian Arctic. Sedimentologic indicators suggest a continental, temperate to arid depositional environment for the Husky Creek Formation, which included fluvial channel belts and floodplains subject to local aeolian winnowing. U-Pb detritalzircon geochronology resolved derivation from rocks related to the Mackenzie Igneous Event, or recycling from older sediments such as the Hornby Bay Group. The Husky Creek Formation was deposited in the waning stages of the Mackenzie Igneous Event, in a restricted basin that was carved atop an extensive mafic volcanic plateau. A dominantly west-northwestward palaeoflow suggests that sediment transport from the core of the Laurentian craton was not significantly disrupted by crustal doming related to large-igneous-province emplacement.

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.
