Precambrian geology, Leith Peninsula-Rivière Grandin area, Northwest Territories
Bibliographic record
Abstract
The Leith Peninsula map area lies along the western margin of the Canadian Shield (Kidd, 1936a) and is dominated by Paleoproterozoic rocks of Wopmay Orogen (Hoffman, 1980, 1989). The oldest rocks, termed Hottah terrane (Hildebrand, 1981), constitute the metamorphic basement to volcanic, plutonic, and sedimentary rocks of the 1.875-1.843 Ga Great Bear magmatic zone (McGlynn, 1979; Bowring, 1985). Hottah terrane is interpreted as a precollisional arc that collided with Slave Craton and its west-facing passive margin during the 1.88 Ga Calderian Orogeny (Hoffman, 1980; Hildebrand, 1981; Bowring and Grotzinger, 1992; Hildebrand et al., 2010a). Rocks of the Great Bear magmatic zone are interpreted as a postcollisional arc, were folded about northwest to northerly trending axes, and are cut by abundant transcurrent faults (Hoffman and McGlynn, 1977; Hildebrand et al., 1987b, 2010b). A swarm of northwesterly trending diabase dykes, dated at 1740 Ma, cut the faults (Irving et al., 2004).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
