New field studies of the Chapperon Group, Vernon southwest map area, British Columbia
Bibliographic record
Abstract
The Chapperon Group comprises a succession of tightly folded metasedimentary and metavolcanic rocks exposed in a southerly-trending belt of five inliers between Westwold and Whiterocks Mountain in south-central British Columbia (NTS 82 L/4W and 82 L/5W). The Chapperon Group rocks are interfolded with rocks of the Upper Paleozoic Harper Ranch Group and are unconformably overlain by the Upper Triassic Nicola Group. The base of the group is unknown. Previous workers have suggested correlations between the Chapperon Group and various units with either pericratonic or oceanic affinities. A new field study was initiated in 1999 to investigate the Chapperon Group with respect to its age, provenance, internal stratigraphy, relationships with adjoining units, and possible correlations with established units in other areas.
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.
