Geological setting of the eastern Bella Coola map area, west-central British Columbia
Bibliographic record
Abstract
Jurassic and Cretaceous magmatic-arc volcanic and sedimentary strata are widely distributed across the eastern Bella Coola map area (NTS 93 D) in two northwest-trending outcrop belts. (?)Lower to Middle Jurassic arc rocks, found in the east, are correlative with the youngest part of the Hazelton Group, distributed widely to the north. Lower Cretaceous volcano-sedimentary strata are found west of the principal Jurassic arc rocks and correlate with the Monarch volcanic deposits, widespread to the south. Plutonic suites of (?) Middle Jurassic, Cretaceous, and Tertiary (Paleogene) ages increase volumetrically westward across the map area. Cretaceous plutonic rocks of ca. 122-119 Ma age may be comagmatic with the Monarch assemblage. East-west extension appears to have characterized both Hazelton Group and Monarch magmatism. Northwest-trending, steeply-dipping ductile shear zones in the central and western parts of the study area involve (?)Jurassic and (?)Cretaceous plutons but are cut by intrusions of Tertiary age.
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.
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.
