Lower Cretaceous stratigraphy and tectonics of eastern Bella Coola map area, southwest British Columbia
Bibliographic record
Abstract
Lower Cretaceous stratigraphic units in the study area consist mainly of flows and fragmental rocks that include basalt and andesite, minor rhyolite and dacite, and epiclastic intervals of sandstone, slate, siltstone, and conglomerate. These rocks are correlated with the Monarch volcanic rocks widespread to the southeast, lie nonconformably on Early Cretaceous plutons, and are interpreted to be deposited onto older plutonic suites. The Cretaceous succession may have formed during east-west crustal extension, and later was tightly to isoclinally and asymmetrically folded to the northeast. The succession appears to have been deposited on an Early Cretaceous topographic high that had sufficient relief to host marine basins and adja-cent subaerial hills. The Hazelton Group appears to be absent beneath the Cretaceous succession. Known mineralization (primarily copper) in the Cretaceous volcano-sedimentary rocks is mainly associated with pluton contacts or fault zones. The slate units almost everywhere have minor disseminated pyrite.
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.
