Surficial geology, Curtis River, Nunavut
Bibliographic record
Abstract
The surficial geology mapping of the southern half of the Ellice Hills map sheet (NTS 56-P-south) was undertaken as part of the Targeted Geoscience Initiative-1 multidisciplinary Committee Bay Project in 2002, and completed in 2010 under the GEM Multiple Metals-Melville Peninsula project. Regional till sampling for matrix geochemistry, kimberlite indicator minerals and gold grain counts were carried out in conjunction with the mapping (McMartin et al., 2003b; Little, 2004). The Ellice Hills-South area lies entirely within the Gulf of Boothia drainage basin. The topography is dominated by broad, terraced valleys, streamlined to rolling till plains, high amplitude hummocky till-glaciofluvial corridors, and rugged bedrock terrain where supracrustal rocks are exposed. In the extreme northwest (NTS 56-P/7-8), gullied plains and veneers of marine sands, silts and clays dominate the landscape. During the last glaciation the area was covered by ice flowing generally northward from the Keewatin Ice Divide located to the south. The limit of marine incursion as the ice retreated is approximately 240-250 m a.s.l. (Giangioppi et al., 2003). The extensive Chantrey moraine system traverses the area from east to west marking a significant stillstand of the retreating ice margin.

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.
