A GIS dataset of geological features from mineral exploration of the Gayna River Property by Rio Tinto Canadian Exploration Ltd., 1975-1976, northern Mackenzie Mountains, Northwest Territories
Bibliographic record
Abstract
Mineral exploration activity by Rio Tinto Canadian Exploration Ltd. in 1975 and 1976 generated good quality bedrock geological maps of the Gayna River Property, in the northern Mackenzie Mountains. These maps were included as part of mineral assessment reports submitted to the government of Northwest Territories. Geological features and observations illustrated in these maps have been digitally rendered into a GIS by the Geological Survey of Canada and are here provided as shapefiles and ArcGIS(TM) layer files for public use. Digitized geological features include: Rio Tinto informal map units, contacts, faults, areas of gypsum outcrop, areas of breccia outcrop, limits of mapping, structural cross-section locations, visited stations, lithologies, planar measurements, linear measurements, and significant mineral occurrences.
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.
