Characteristics of Mesoarchean and Neoarchean suprascrustal sequences at the southern margin of North Caribou terrane in the Wallace Lake greenstone belt, Superior Province, Canada
Bibliographic record
Abstract
The Wallace Lake greenstone belt is located on the southern margin of the Uchi-Sachigo-Goudalie superterrane within the volcanic-rich Uchi subprovince of the Superior Province in southeastern Manitoba, Canada. Its stratigraphy consists of a Mesoarchean complex constituted of alluvial conglomerate derived from ca. 3000 Ma tonalite, overlain by a crustal contaminated mafic-ultramafic volcanic sequence. Both units were deformed and then intruded by a 2.92 Ga tonalite body and related dyke swarm. Thrust sheets of a tholeftic volcanic sequence of unknown age, of oceanic plateau affinity tectonically overlie this Mesoarchean complex. The tectonic assembly was associated with regional SW directed compression, resulting in NW-trending folding and faulting. No metamorphic break is observed within this tectonic package despite major faulting related to this event. Neoarchean (<2709 Ma) greywacke and polymictic conglomerate unconformably overlie these units, and were deformed by dextral transcurrent deformation. Finally, fault bounded low-strain alluvial greywackes mark the last recorded stratigraphic and structural event affecting this area.

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.
