Devonian Granite Melt Transfer in Western Maine: Relations Between Deformation, Metamorphism, Melting and Pluton Emplacement at the Migmatite Front
Bibliographic record
Abstract
The northern Appalachians are divided into NNE-SSW-trending tectonostratigraphic units (Figure 1).The Central Maine belt (CMB), continuous with the Central Mobile belt in Maritime Canada, is the principal unit that occupies most of the eastern part of New England and New Brunswick.The CMB is composed of a Lower Paleozoic sedimentary succession, deformed and metamorphosed at greenschist to upper amphibolite facies conditions, and intruded by plutons of Devonian age (e.g.Moench et al., 1995;Bradley et al., 1998;Solar et al., 1998).The CMB is located between Ordovician rocks of the Bronson Hill belt (BHB) to the W and NW that were deformed and metamorphosed during the Ordovician Taconian orogeny, prior to deposition of the CMB sedimentary sequence.To the SE of the CMB, rocks are Neoproterozoic to Silurian age of the Avalon Composite terrane (ACT).Regional deformation was partitioned heterogeneously during dextral transpression in response to Early Devonian oblique convergence (van Staal and de Roo, 1995;van Staal et al., 1998).Dextral-SE-side-up

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.
