New insights into metavolcanic successions and geochemistry of the Eagle Bay Assemblage, south-central British Columbia
Bibliographic record
Abstract
The Eagle Bay Assemblage of the Kootenay Terrane in the Johnson and Adams lakes area comprises deformed, greenschist-facies sedimentary rocks and bimodal volcanic rocks. Two volcanic successions are present, an Upper Devonian mafic and felsic metavolcanic succession and a Lower Cambrian mafic metavolcanic succession. The latter is interbedded with archaeocyathid-bearing carbonate rocks. Upper Devonian U-Pb zircon ages of 360 ± 6 Ma have been obtained for felsic metavolcanic rocks of the bimodal succession. Lithogeochemical analyses of the metavolcanic rocks have identified two distinct metabasic successions. Mafic metavolcanic rocks of the Upper Devonian bimodal succession are alkalic, whereas Cambrian mafic metavolcanic rocks are subalkaline. The mafic metavolcanic rocks of the bimodal alkalic succession are associated with base- and precious-metal occurrences, such as the Rea, Samatosum, and Homestake deposits.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
