Abstract
Ancient (>3.7 Ga) detrital zircons represent some of the few remaining relicts of Earth's earliest evolution. A metagreywacke from the northwestern margin of the Superior Province, Canada, has abundant Paleoarchean detrital zircon with peaks in age distribution at 3.86, 3.79, 3.74, and 3.32 Ga. A fuchsitic quartzite from the western margin of the Rae Province, Canada, contains entirely Paleoarchean detritus with peaks in age distribution at 3.86, 3.76, and 3.72 Ga. Both samples contain a small (2%–4%) proportion of zircon grains that are ≥3.9 Ga. Hf isotopic analysis indicates that a large proportion of the Paleoarchean zircon from both samples...

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 it
