Reconnaissance surficial geology, Overby Lake, Nunavut, NTS 76-I
Bibliographic record
Abstract
Preliminary surficial geology studies, based on air photo interpretation and limited field data, were undertaken in the Overby Lake map area to provide an understanding of the distribution and nature of surficial materials, and regional glacial history. Much of the western area is characterized by rubble-covered bedrock containing shallow glacially scoured lake basins. Streamlined rock and till landforms indicate ice flow towards the northwest and north-northwest. Till blankets and veneers have a pebbly silty-sand matrix, but their surfaces tend to be bouldery where they were affected by glacial meltwater. Subglacial meltwater corridors consisting of eskers, washed till, boulder lags and scoured bedrock, cross the entire area. The MacAlpine Moraine in the southeast formed during glacial recession about 8200 years ago, and is defined by hummocky till, kames, and related glaciofluvial outwash. Sandy postglacial marine sediments extend up Ellice River to 220 m a.s.l. In the northeast, below 190 m a.s.l., silty marine deposits form extensive plains between drumlinoid ridges in the Queen Maud Bird Sanctuary.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
