Geology of the Archean Rae Craton and Mary River Group and the Paleoproterozoic Piling Group, central Baffin Island, Nunavut
Bibliographic record
Abstract
New mapping (NTS 27 B, C, 37 A, D) has characterized the supracrustal rocks of the Archean Mary River Group and their relationship to the underlying Archean basement orthogneiss units of the Rae Craton. The primary depositional unconformity that separates the base of the Paleoproterozoic Piling Group from the Rae Craton basement has been documented across the project area. The basal, clastic Dewar Lakes formation has been subdivided into 3 informal members. Significant primary variations in thickness of the Dewar Lakes and carbonate Flint Lake formations have been identified throughout the project area. Mafic volcanic rocks and ultramafic to mafic sills interlayered with siliciclastic rocks (Bravo Lakes formation) overlie the basal clastic rocks. Sulphidic pelite (Astarte River formation) overlies the three lowest formations. Psammite-pelite turbidite units (Longstaff Bluff formation) blanket the entire area, and are interpreted as an orogenic molasse. Deformation and consequent metamorphism occurred during the 1.8 Ga Trans-Hudson Orogen.

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.
