Nature and significance of deformation zones on gold mineralization in the Detour Lake area: implications for exploration in Ontario and Quebec
Bibliographic record
Abstract
The Detour Lake gold mine and Lower Detour zones (e.g. Zone 58N and Zone 75) are located in the northwestern part of the Abitibi greenstone belt and are hosted in a volcanic sequence of the 2.73 to 2.72 Ga Deloro assemblage or in altered feldspar porphyry intrusive(s). Mineralization consists of low-grade disseminated quartz-sulphide zones and silicified high-grade zones, including laminated quartz-tourmaline-carbonate veins and stockworks. Ore zones are commonly oriented sub-parallel to a series of high-strain zones occurring co-planar and in the hanging wall to the regional-scale Sunday Lake and Lower Detour deformation zones. The latter zone has a close spatial relationship with polymictic conglomerates and intermediate to felsic intrusive rocks, which is analogous to major fault systems of the Timmins-Porcupine area and associated syn-orogenic Timiskaming conglomerates. The focus of this study is to examine the relationships between gold mineralization and deformation in the Detour Lake region and in Quebec and compare these with those of the southern Abitibi.

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.
