Revised geological framework for the McFaulds Lake greenstone belt, Ontario
Bibliographic record
Abstract
The McFaulds Lake greenstone belt (MLGB) is an extensive (>200 km long), arcuate-shaped, Meso- to Neoarchean, greenstone belt located in the central part of the Oxford-Stull domain of northern Ontario. The MLGB records a history of episodic volcanism, sedimentation, ultramafic-felsic intrusive activity and tectonism spanning from at least 2.83 to 2.66 Ga. Supracrustal rocks are tentatively subdivided into 7 tectonostratigraphic assemblages based on mapping, U-Pb geochronology, and geophysical interpretation. Mafic and ultramafic intrusive rocks comprise at least two distinct suites: a mafic-dominated, large layered intrusive suite represented by the Highbank-Fishtrap intrusive complex that was emplaced at ca. 2810 Ma, and an ultramafic to mafic intrusive suite termed the Ring of Fire intrusive suite. The latter comprises an ultramafic-dominated subsuite with significant Cr-Ni-Cu-PGE mineralization, and a mafic-dominated subsuite that contains significant Fe-Ti-V-(P) mineralization that was emplaced at ca. 2734 Ma.
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.
