Nicola Horst, southern British Columbia: window into the pre-Triassic margin of North America?
Bibliographic record
Abstract
The Nicola Horst, in the Intermontane Belt of British Columbia, is separated from surrounding volcaniclastic rocks of the Late Triassic Nicola Group by steep brittle Tertiary faults. It includes metavolcanic units correlative with the Nicola Group and quartzite metaconglomerate and graphitic metapelite that are probably older, intruded by mafic and granitic rocks ranging in age from Palaeocene to latest Triassic. Supracrustal rocks and early metatonalite are strained, metamorphosed to amphibolite facies, and truncated by less-deformed plutonic units. The horst provides a window into the middle crust and perhaps below the base of the Nicola Group. Siliciclastic metasedimentary rocks are similar to units exposed to the east, in Vernon map area, postulated to represent a stratigraphic link between the Triassic rocks of Quesnellia and the late Proterozoic early Paleozoic margin of North America. If the proposed correlations are valid, North American basement extends at least as far west as the Nicola Horst.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
