Stratigraphic framework for the Cambrian Chaudière Nappe in the external domain of the Humber Zone in the Quebec Re-entrant, and preliminary correlation with adjacent stratigraphic frameworks
Bibliographic record
Abstract
The Chaudière Nappe is limited to the north by the Logan's Line and associated mélange units, and to the south by the Foulon Fault. Sedimentary units of the Chaudière Nappe form the Sillery Group which consists of the Sainte-Foy, Saint-Nicolas, and Breakeyville formations. The biostratigraphic information suggests that the Saint-Nicolas Formation is Early Cambrian. The Sainte-Foy Formation tectonically underlies the Saint-Nicolas Formation, the former consists predominantly of variously coloured mudstone. The Saint-Nicolas Formation is divided into three units: a lower massive and coarse-grained sandstone, a middle cyclic turbidite, and an upper red mudstone. The Breakeyville Formation consists of two units, a lower conglomerate-sandstone and an upper mudstone-sandstone. Correlation with adjacent stratigraphic frameworks is based on the recognition of the massive lower unit of the Saint-Nicolas Formation in other successions, and on correlation of the lower conglomerate of the Breakeyville Formation with Upper Cambrian conglomerate in eastern Quebec.

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.
