Glacial geomorphology and till geochemistry of southern Melville Peninsula, Nunavut
Bibliographic record
Abstract
This report presents results from field work on southern Melville Peninsula during 2010, part of Geo-Mapping for Energy & Minerals (GEM) Multiple-metals - Melville Peninsula Geoscience Project. Along the coast of the peninsula, ice flow was warm-based and seaward during late-glacial and deglacial time. Across the Rae Isthmus, ice flow was northward and reversed to the south along the southern coast during deglacial time. Ice-flow history and glacial geomorphology show that on the central part of Southern Melville, some cold-based regions persisted during the last glaciation, and elsewhere the glacial regime was permanently or intermittently warm-based during that period. Complementing extensive pre-existing research, a focused drift sampling survey was conducted to assist mineral exploration in regions underlain by prospective bedrock but mantled by glacial deposits of varying thickness. The silt-sized till matrix geochemistry, the heavy mineral concentrates from till mineralogy and mineralized erratic boulders were analyzed for base metals, gold, uranium, gemstone and diamond potential.

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.
