Geological setting of the Samatosum and Rea massive-sulphide deposits, Eagle Bay Assemblage, south-central British Columbia
Bibliographic record
Abstract
Highly deformed, low-grade metamorphic sedimentary and volcanic rocks of the Eagle Bay Assemblage host the (?)volcanogenic massive-sulphide Twin Mountain, Samatosum, and Rea deposits. The Twin Mountain deposit comprises sulphide-bearing quartz-carbonate-barite lenses in sericitized and silicified schists of volcanic origin. The Rea deposit consists of at least two massive-sulphide lenses. The Samatosum deposit is an overall stratabound sulphide-rich quartz-vein system that could be interpreted as a stockwork zone. The Rea and Samatosum deposits occur within an overturned metasedimentary sequence of sericitized and silicified argillites structurally overlain by mafic volcaniclastic rocks and flows. The stratigraphic sequences at Rea and Samatosum are very similar. We suggest that structural repetition by faulting occurred, and that the sedimentary and volcanic succession is Devonian-Mississippian.

How this classification was reachedexpand
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.
