Initial rifting of the Archean nucleus of North America in eastern Canada is constrained to have been diachronous between 2.17 and 2.03 Ga. Renewed rifting of a segment of the continental margin, 292 to 120 m.y. later, was accompanied by the emplacement of ultramafic layered sills, the accumulation of komatiitic and alkalic basalts, the deposition of banded iron formations and the isolation of a microcontinent and its 1.93 Ga continental shelf succession (subsequently accreted to the telescoped continental margin during collisional orogenesis).

Full frame distilled prediction

Teacher imitation

Not 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.
