Distribution of Cambrian formations in the eastern Mackenzie Mountains, Northwest Territories
Bibliographic record
Abstract
New bedrock mapping in the eastern Mackenzie Mountains (NTS 96 D and 96 E) has clarified the distribution of Cambrian formations northeast of the Mackenzie arch, notably by confirming the presence of the Lower Cambrian Mount Clark Formation. Mount Clark Formation is resistant weathering, dominated by quartz arenite, and commonly burrowed. It lies unconformably upon the Proterozoic Mackenzie Mountains Supergroup and is gradationally overlain by the Early Cambrian Mount Cap Formation. Numerous exposures previously mapped as Mount Cap Formation have been reassigned to Mount Clark Formation. Distinction between Mount Clark Formation and Proterozoic quartz sandstone units is aided by differences in colour and cementation, and particularly by the presence of burrows in the younger unit, a feature not present in older rocks. Mount Clark Formation is a hydrocarbon reservoir facies elsewhere in the Mackenzie Corridor. Improved understanding of its regional distribution may contribute to improved exploration success.

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.
