Revision mapping of the Yukon-Tanana and equivalent terranes in northern British Columbia and southern Yukon Territory between 131° and 132°W
Bibliographic record
Abstract
The northern half of the Jennings River (104-O) and southern half of the Wolf Lake (105 B) map areas include multiply deformed and metamorphosed rocks of the eastern Big Salmon Complex (Yukon Tanana Terrane) and a succession of mostly Paleozoic rock assemblages whose terrane affinity is in question. Hazel Ridge, on the west side of the area, reveals folded mafic metavolcanic rock, piedmontite chert, and marble in a series of overturned isoclinal folds. This consistent stratigraphic succession is overlain by metagreywacke on a possible unconformity. In the northeast, siliceous gritty and mafic metavolcanic rocks of the Dorsey assemblage are intruded by orthogneiss. These are overlain on a probable detachment fault by thin mafic volcanic rock and limestone ((?)Klinkit assemblage) and by dark phyllitic rocks and quartzite (Swift River assemblage). Both Hazel Ridge and the Dorsey assemblage contain several quartz±feldspar-phyric siliceous layers that suggest volcanogenic massive-sulphide potential.

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.
