Stratigraphy and structures within the Lower to Middle Jurassic Hazelton Group, Takysie Lake and Marilla map areas, central British Columbia
Bibliographic record
Abstract
Deformed Hazelton Group rocks in southern Takysie Lake (NTS 93 F/13) and northern Marilla (NTS 93 F/12) map areas consist of maroon to reddish-brown polymictic cobble conglomerate; red, pebbly mudstone; and feldspathic lithic wacke. The strata form the upper plate of a northwest-trending, southwest-dipping reverse fault. The rocks commonly dip moderately to the north, are locally folded about a northwest-trending fold axis, and are penetratively deformed. A closely spaced S1 cleavage dipping moderately southeast and a less well developed S2 cleavage dipping steeply west represent the oldest recognized structures in the region. The lower plate consists of Jurassic Bowser Lake or Cretaceous Skeena groups chert-rich greywacke and polymictic chert- and felsic volcanic-rich conglomerate exhibiting an east-trending, moderately dipping cleavage. Hanging wall and footwall rocks are intruded by the undeformed (?)Late Cretaceous Skins Lake pluton, constraining the timing of deformation to post-Jurassic and pre-(?)Late Cretaceous.
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.
