Refining lithological and structural understanding of the southern Core Zone, northern Quebec and Labrador in support of mineral resource assessment
Bibliographic record
Abstract
Integrated mapping of the southern New Québec Orogen - Core Zone as part of the second phase of Geomapping for Energy and Minerals (GEM-2) is providing insight into the collisional orogen between the Superior and North Atlantic cratons by investigating the composition, age and architecture of intervening crust at a scale that will bridge knowledge of Archean and Paleoproterozoic tectonomagmatic evolution across the Quebec - Labrador border. In 2014, bedrock mapping of seventy-five localities investigated clastic and carbonate rocks of the Kaniapiscau Supergroup (eastern Labrador Trough), mafic metavolcanic rocks of the Doublet Zone, granitoid basement and unconformably overlying metasedimentary rocks of the Laporte domain, orthogneissic basement and the cross-cutting 1837-1820 Ma De Pas Batholith, and a collage of supracrustal rocks and associated gabbroic plutons that attain upper amphibolite to granulite facies (migmatitic Mistinibi domain) east of the De Pas batholith. 2014 observations were assessed in light of previous understanding of this region and a number of questions or knowledge gaps were identified which formed the basis for supporting laboratory analysis and targetted mapping in 2015. Bedrock findings are being integrated with surficial mapping, till analysis and glacial dispersion studies, collectively contributing knowledge for increased exploration effectiveness across this part of Quebec and Labrador.

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.
