Evolution of the Coast Cascade Orogen by Tectonic Thickening and Magmatic Loading: The Cretaceous Breakenridge Complex, Southwestern British Columbia
Bibliographic record
Abstract
A model for the tectono-magmatic mid-Cretaceous (110-80 Ma) evolution of the southern Coast belt is proposed. The first magma pulse represented by the 107-100 Ma Breakenridge pluton intruded within a magmatic arc as a set of shallow sills. It was initially buried by orogen-parallel contraction, followed by the emplacement of the 96-94 Ma Snowshoe pluton, which belongs to the second magma pulse. The Snowshoe pluton was emplaced by similar mechanisms in structurally higher levels of the crust. Orogen-normal compression was the final mechanism for deep burial and attainment of peak metamorphic conditions (500-680°C at 6.5-10.3 kbar) of the study area between 91-86 Ma. Following orogen-normal contraction and regional folding, oblique right-lateral strike-slip shearing occurred while rocks were in a ductile environment. The third magma pulse (86-84 Ma) was synchronous with the late stages of high-grade metamorphism and early stages of oblique strike-slip movement.

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.
