Tracking the Wakeham Group volcanic rocks and associated copper-iron oxide hydrothermal activity from La Romaine eastward, eastern Grenville Province, Quebec
Bibliographic record
Abstract
The last field season of the Targeted Geoscience Initiative Eastern Grenville Transect in Quebec unveiled a < 10 km wide by 50 km long southeastern extension of the Wakeham Group, host to an extensive cupriferous hydrothermal system. The supracrustal rocks consist of granulite-facies metasandstone, 1.5 Ga lapillistone, amphibolite, marble, and calc-silicate rock enclosed within a metamorphosed, 1.5 Ga Pinwarian subvolcanic batholith. High-grade metamorphism in this belt would traditionally be seen as an impediment to mineral exploration. However, we have recognized and traced an extensive zone of aluminous gneiss that records strong hydrothermal leaching of metavolcanic units. Amphibolite occuring structurally above and likely serving as a caprock contains garnetite, diopsidite, and hornblendite and provides an effective guide to the site of fluid discharge and mineralization.Anumber of showings were discovered; their systematic occurrence, in a structural and stratigraphic sense, suggests that, although this supracrustal belt is of modest size, it should be explored.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
