Lead-zinc showings associated with debrite shed from synsedimentary faults, Mesoproterozoic Society Cliffs Formation, northern Baffin Island, Nunavut
Bibliographic record
Abstract
Showings near the Adams River valley on northern Baffin Island are hosted by lowermost strata of the Mesoproterozoic Society Cliffs Formation. They are characterized by galena, sphalerite, iron sulphide, sparry dolomite, diagenetic quartz, and bitumen. Host rocks are terrigenous dolo-wacke debrite and turbidite shed from fault blocks that were active during sedimentation, and crackle to rubble breccia in the featureless brown dolostone that encloses the debrite and turbidite lobes. Although the late breccia that contains sulphide mineralization is visually similar to early (synsedimentary) breccia, it can be distinguished from the latter by examining the interstitial fill: early brecciation is associated with finely crystalline, pale dolomite, whereas late brecciation is associated with coarse sparry dolomite. The structural, stratigraphic, and sedimentological controls on mineralization at Adams River may be similar to those at other, hitherto unstudied showings in the Borden Basin, as well as the Nanisivik deposit.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
