Quartzite sequences and their relationships, Woodburn Lake group, western Churchill Province, Nunavut
Bibliographic record
Abstract
Archean orthoquartzite units of the Woodburn Lake group are part of a diverse volcanic and volcanogenic sedimentary package, in contrast to the cratonic sedimentary rocks of the Paleoproterozoic Amer group. Woodburn Lake quartzite is interbedded with pyritic quartz-pebble conglomerate, chloritoid-kyanite slate, and iron-formation, none of which have been described from the Amer group. Pyritic conglomerate presents a potential for paleoplacer and modified placer gold, which could have had a local source in underlying mineralized volcanic and sedimentary rocks. The presence of pyritic conglomerate is consistent with deposition in the reducing atmosphere characteristic of Archean time and may prove to be a diagnostic tool for discriminating Archean from Paleoproterozoic quartzite successions in the region. Archean ultramafic rocks and gossanous iron-formation can be traced discontinuously south of the Amer belt, considerably extending the strike-length of the suite, which is known to host gold occurrences.

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.
