Abstract
The geology of the Wijinnedi Lake area, presented as a 1:50 000-scale map sheet (Map 2023A) in the southwestern Archean Slave Province, is divided into four lithotectonic domains. The three western domains are separated by Archean ductile shear zones. In the northwest, the structurally highest Wijinnedi domain consists of a 2670 Ma Yellowknife Supergroup felsic volcanic centre, partly mantled by more mafic volcanic rocks that are overlain by a tightly to isoclinally folded, pelite-dominated siltstone and finegrained greywacke turbidite sequence. Metamorphic grade in the lower pressure facies series ranges from lower greenschist to middle amphibolite, but reaches migmatite grade locally at the east end of the domain. To the south, the Hinscliffe domain consists mainly of a polyphase, largely recrystallized, ca. 2.65 Ga trondhjemite complex intruded by mafic amphibolite synplutonic dykes. To the southeast, the Ghost domain, representing mid-crustal structural levels, is dominated by plutonic bodies, with the areally most extensive tonalite and related tonalite gneiss intruded about 2.64 - 2.63 Ga and a group of mainly granite intrusions emplaced at about 2.60 Ga. The less abundant Yellowknife Supergroup pelitic metasedimentary rocks and intermediate volcanic rocks are represented by migmatite. Most of the domain is at granulite grade with most of the plutonic bodies crystallizing under granulite-grade conditions. The Dauphinee domain in the eastern part of the area is separated from the high-grade rocks to the west by a Paleoproterozoic cataclastic shear zone; it consists mainly of quartz dioritic to granitic rocks and minor metasedimentary migmatite that are not at granulite grade.

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.
