Revised stratigraphy and sedimentology of the Paleoproterozoic Dubawnt Supergroup at the northern margin of Baker Lake Basin, Nunavut
Bibliographic record
Abstract
On the northwest side of the Paleoproterozoic Baker Lake basin the Christopher Island Formation, comprising volcanic flows intercalated with alluvial fan and pyroclastic rocks, unconformably overlies Archean gneiss. It is unconformably overlain by the Amarook Formation (new name), a well indurated sandstone characterized by large-scale crossbedding of probable eolian origin, and interbedded alluvial sandstone and conglomerate. The Amarook Formation correlates with similar strata recognized in drill core and outcrop from the eastern Thelon Basin. The disconformably overlying Pitz Formation includes lower volcanic and upper sedimentary members. The upper member correlates with strata mapped as basal Thelon Formation in the Thelon Basin. Lower Dubawnt Supergroup rocks are offset by a series of northwest-striking dextral faults that may predate deposition of the overlying Barrensland Group. A possible strike-parallel fault may be responsible for repetition of lower Dubawnt strata in the southern part of the study area.

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.
