The Wolves Islands : a missing link in southern New Brunswick geology
Bibliographic record
Abstract
The Wolves Islands are located in the Bay of Fundy, approximately 10 km offshore from mainland southwestern New Brunswick. They are located in a geologically complex area through which it is difficult to trace rock units and terranes from New Brunswick into the state of Maine (USA). Because of their offshore location, The Wolves may provide the missing link in these correlations. Geological mapping in 2004 and 2005 and subsequent petrological studies revealed that The Wolves are underlain mainly by rocks monzodiorite, gradational to quartz monzodiorite with minor tonalite and quartz monzonite, herein termed collectively The Wolves pluton. Varied meta-igneous xenoliths are abundant, and rare syenite dykes and scattered mafic dykes intrude the pluton. Samples from The Wolves pluton range in silica concentration from 47.6% to 59.6% in the monzodiorite unit, 65.4% to 73.3% in the tonalite, and 69.01% in the quartz monzonite. The xenoliths are generally similar in mineralogy and chemical composition to the monzodiorite and range in silica concentration from 49.2% to 54.7%. Based on continuity of chemical trends, the monzodiorite, tonalite, quartz monzonite and xenoliths are interpreted to be co-magmatic. They constitute a calc-alkalic, I-type granitoid suite that formed in a volcanic arc setting. A sample of quartz monzodiorite from East Wolf Island yielded an Early Silurian U-Pb age of 437±5 Ma, showing that The Wolves are not related to the Late Neoproterozoic plutonic rocks of the Caledonia and Brookville terranes. The age is similar to that of the volcanic and plutonic units of the Kingston terrane. Although the rocks on The Wolves differ petrologically from those of the Kingston terrane, chemical similarities suggest that The Wolves may represent a deeper part of the Kingston volcanic arc.

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.
