Abstract

fetched live from OpenAlex

À environ 150 km au NE de Tadoussac, le cap Colombier apparaît comme le site le plus oriental connu de la dispersion des erratiques de dolomie sur la rive nord de l'estuaire maritime du Saint-Laurent. Une cinquantaine de cailloux de dolomie de diverses catégories ont, en effet, été observés sur le bas estran argileux du havre du Colombier. La taille des cailloux va de 7 à 320 cm (axe-a). Si le plus gros bloc pèse environ 20 tonnes, les autres sont beaucoup plus petits : les dix plus gros pesant entre 33 et 345 kg. Il y a environ 12 % de cailloux de dolomie cristalline de couleur rose et 20 % des cailloux sont striés. Un bloc de dolomie partiellement bréchique contenait des structures stromatolitiques. La source la plus vraisemblable demeure le bassin sédimentaire de Mistassini situé à environ 500 km au NO, ce qui implique, dans un premier temps, un transport glaciaire par un courant de glace à partir d'un dôme localisé au NO du lac Mistassini, puis, dans un deuxième temps, une mise en place par des icebergs dans la Mer de Goldthwait probablement issus de la langue glaciaire canalisée dans le Saguenay.

Not 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.
