Upper Cambrian to Lower Silurian stratigraphy of a Macdonald Platform-Kechika Trough-Cassiar Terrane transect, Ware, Tuchodi Lakes, Kechika, and Cry Lake map areas (94-F, K, L, 104-P), northeastern British Columbia
Bibliographic record
Abstract
The Kechika Formation, a laterally extensive platform-to-basin facies, typically lies unconformably on Cambrian strata. Its five members, which are diachronous, have gradational and conformable contacts. Basinal facies of the Road River Group comprise three formations: the Ospika (Lower to Middle Ordovician), Pesika (Lower Silurian), and Kwadacha (upper Lower Silurian to Lower Devonian). Volcanism, prominent unconformities, and abrupt changes in deposition indicate a complex history delineated temporally by conodont biostratigraphy. Deposition of the Kechika and Ospika formations is attributed to periods of renewed extension followed by thermal subsidence. Silurian units unconformably and conformably overlie the Ospika Formation. The Pesika Formation, a transitional facies, is present mainly in the eastern part of the Kechika Trough. The Kwadacha Formation records an influx of quartz silt and sand into the trough. The Kechika-Road River boundary in the displaced Cassiar Terrane is older than that east of the Northern Rocky Mountain Trench Fault.
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.
