Lithogeochemical studies in the Uchi Confederation greenstone belt, northwestern Ontario: implications for Archean tectonics
Bibliographic record
Abstract
The Uchi-Confederation greenstone belt consists of three volcanic units that span over 250 million years (2989-2735 Ma) that have previously been termed the Balmer, Woman, and Confederation assemblages. Recent geochemical data indicate that the ca. 2840 Ma rocks of the Woman assemblage may be absent from this greenstone belt. The western portion of the group previously interpreted as the Woman assemblage are actually ca. 2880 Ma basaltic volcanic rocks, referred to herein as the Narrow Lake assemblage, whereas the eastern portion is probably part of the Confederation assemblage. Structural and geochronological studies indicate that the volcanic strata formed in situ rather than having been juxtaposed tectonically. The distribution, structure, and geochemistry of units within the Confederation assemblage (ca. 2740 Ma) indicate that it formed as a rifted arc. However the tectonic settings of the older volcanic units are ambiguous.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
