Granite-greenstone relationships at the southeastern Sturgeon belt margin in the Brightsand forest area, Ontario
Bibliographic record
Abstract
At the southeastern margin of the Sturgeon Lake-Savant Lake greenstone belt, screens of amphibolite-facies supracrustal rocks, separated by plutonic and gneiss units, mark the interface between volcanic rocks of the western Wabigoon and granitoid rocks-gneiss of the central Wabigoon Subprovince. Complex tonalite gneiss records D1 and D2 events not present in supracrustal and other plutonic units which sustained regional D3 and D4 deformation. The complex gneiss may represent depositional basement to supracrustal rocks correlative with the continental margin sequence of the Sturgeon-Savant belt. Alternatively, the fold geometry of this unit can be explained by large-scale fold interference. The steeply north-dipping Hilltop Creek and Robert Lake faults, which appear on LITHOPROBE seismic line 1d as steep truncations, separate the region into metamorphically and lithologically distinct structural panels. The faults are spatially and probably mechanically related to the sinistral Wapikamaiski Lake and Brightsand River shear zones.

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.
