Structural investigation of an exposure of the Teslin Fault, northwestern British Columbia
Bibliographic record
Abstract
In the Teslin Lake map area (NTS 104-O), northwestern British Columbia, the steeply oriented Teslin Fault juxtaposes Cache Creek Terrane ribbon chert and wacke against mafic metavolcaniclastic and meta-intrusive greenstone of the Yukon-Tanana Terrane. A section ~250 m wide of washed, almost continuous, exceptional exposure along the Jennings River is oriented at high angle to the southeasterly trending steep fault zone. Structural analysis reveals two episodes of shearing. Dominantly transcurrent, sinistral ((?)transpressive) motion (D1), indicated by a variety of shear-sense and sense-of-vorticity indicators, was associated with pervasive (ultra)mylonitization in the greenstone package. A younger set of more localized, dominantly brittle(-ductile) structures overprinting D1 fabrics probably formed during dextral transpression (D2). D1 deformation was penetrative in the Yukon-Tanana rocks; however, it did not (significantly) affect the currently exposed Cache Creek rocks. Juxtaposition of these differently D1-strained rock packages is attributed to D2.

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.
