Field data, till composition, and ice-flow history, south Rae Craton, Northwest Territories: results from the GEM-2 South Rae project - Surficial Mapping activity
Bibliographic record
Abstract
This report releases new field data and analytical results from regional surficial geological mapping and till sampling surveys completed in 2014 to 2016 in the southeast corner of the Northwest Territories as part of Natural Resources Canada's South Rae Activity, GEM-2 Rae project. The report also provides a summary of the regional bedrock and surficial geology, a detailed description of the field and analytical methods and a preliminary discussion of regional glacial transport. In total, Quaternary geological field observations were made at 646 sites; 205 till, 3 esker and 21 geochronology samples were collected over the 3 years. Samples were analyses for matrix geochemistry and texture, gold grain counts, indicator mineral picking and probing, and pebble lithology counts. Highlights include the 5 phase ice flow chronology, and comments on glacial transport dispersal history and on till geochemical masking due to due to the dilution effect of SiO2 (sandstone quartz).
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.
