Preliminary interpretations of mid-Jurassic volcanic and sedimentary facies in the east Telegraph Creek map area
Bibliographic record
Abstract
On the basis of regional-scale and reconnaissance mapping, strata similar in age and character to those hosting the Eskay Creek precious-metal-rich, volcanic-hosted massive sulphide deposit are considered to project northward into the east Telegraph Creek map area. Detailed volcanic- and sedimentary-facies mapping in that area in 2003 has identified a variety of subaqueous volcanic and sedimentary facies of probable Lower or Middle Jurassic age. Subaqueous volcaniclastic and nonvolcanic clastic rocks dominate the field area. Coherent volcanic and associated volcaniclastic facies occur in several areas and are considered to indicate proximity to volcanic centres. The presence of marine fossils, sediment gravity-flow deposits, and pillow basalt provide evidence for a submarine environment; the lack of shallow-water sedimentary structures indicate that the environment of deposition was below wave base.

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.
