Hydrothermal Alteration of a Breccia Pipe Deposit,
Bibliographic record
Abstract
The Tribag mine is situated approximately 45 miles north-northwest of Sault Ste. Marie, Ontario. Precambrian rocks exposed in the area consist of: silici to basic metavolcanics, metasediments and iron formations; granite; diabase dikes and sills; and a series of olivine basalts interlayered with conglomerate and sandstone. The metavolcanics, metasediments, and iron formations represent an accumulation of 30,000 feet of material that was later intruded by granitic batholiths. All of these rocks are faulted and intruded by diabase dikes and sills. A thick series of olivine basalts was extruded into the Lake Superior basin. Conglomerate and sandstone are interlayered with the basalts, which dip southwest at 20 to 40 degrees. Felsite bodies intrude the volcanic and sedimentary layers. The Tribag mine is in the Breton breccia, one of five breccia pipes near the eastern margin of Township 28, Range 13. The pipe has surface dimensions of 1,400 by 350 feet, and the size increases slightly with depth. The breccia contains angular to sub-rounded fragments of trondhjemite or sodic granite, basic volcanics, felsite, and diabase.

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.
