Bedrock mapping in the Walmsley Lake area, southeastern Slave Province, Northwest Territories
Bibliographic record
Abstract
Bedrock mapping in the Walmsley Lake map sheet (NTS 75 N) was completed during the 2002 field season. Highlights include the identification and delineation of an Archean mafic to ultramafic gabbro-anorthosite suite, and delineation and closure of the Cook volcanic belt. Deformation fabrics in the southern and western portions of the map sheet, where mapping was concentrated in 2002, define broad, open domes and basins, and metamorphic assemblages indicate temperatures above minimum melting conditions. Field relationships suggest the peak of metamorphism and synmetamorphic deformation occurred later in this area than farther north, where greenschist facies assemblages formed before ca. 2605 Ma. Mapping of Proterozoic mafic dykes revealed evidence that at least two dyke swarms may have seen multiple generations of intrusion. The fracture systems that host the mafic dyke swarms may have served as conduits for more than one generation of mantle-derived magma.
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.
