Tectonostratigraphy, structure, and geochemistry of the Mesoarchean Wallace Lake greenstone belt, southeastern Manitoba
Bibliographic record
Abstract
In the Wallace Lake greenstone belt, the Conley and Overload Bay formations make up the Wallace Lake assemblage (<3.0 Ga, >2.92 Ga), and comprise a platformal sedimentary sequence and an associated mafic-ultramafic volcanic sequence with iron-formation. The Big Island composite assemblage contains three superposed tectonic slivers comprising mafic-ultramafic rocks, gabbro, and pillow lavas. The Siderock Lake assemblage comprises volcanogenic polymictic conglomerates. Geochemically, mafic-ultramafic rocks low in the stratigraphy appear to be contaminated, whereas upper units do not. The Wallace Lake, Big Island composite, and Siderock Lake assemblages are separated by layer-parallel D1 high-strain zones which are folded by northwest- and west-trending close and reclined D2 folds. Dextral shearing and east-northeast-trending folds represent a D3 event, and D4 produced S-shaped kink bands within older high-strain zones.
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.
