Slab break-off triggered minor within-plate volcanism. The Acadian foreland system, prominent in Maine, propagated northwestward following the docking of Avalon. Two examples from Maine illustrate how Appalachian tectonics may contribute to a general understanding of tectonicclimate linkages. First, Penobscot orogeny and the emergence of the New Caledonian ophiolite share much in common. The latter event coincided with the onset of Antarctic glaciation at 34 Ma. In both cases, the exhumation of soluble basic and ultrabasic rocks caused sequestering of atmospheric carbon dioxide through silicate weathering and organic carbon burial. For the 34 Ma event, a rapid trigger is needed to explain the climatic overshoot, and slab breakoff seems a plausible candidate. Second, near Farmington, a recently discovered slumped horizon rests directly on black shales, suggesting a methane release trigger for the slump. This relationship resembles the mechanism invoked for terminal Paleocene extinction, the best ancient analog for the worst-case future global warming scenario.

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.
