New insights into the geological history of the basement rocks to the southwestern Athabasca Basin, Saskatchewan and Alberta
Bibliographic record
Abstract
Much of the basement to the southwest Athabasca Basin comprises rocks of the Lloyd Domain. These include the Careen Lake Group, a melange of metasedimentary rocks, parts of which are correlative with Archean Murmac Bay Group and Rutledge River Basin rocks. These rocks were intruded by ca. 1985 - 1968 Ma plutons of the Taltson magmatic zone. The Lloyd Domain was divided by weakly deformed 1843 Ma granite and 2500 Ma granitic gneiss of the Clearwater Domain. To the east, supracrustal rocks of the 'Virgin schist group' are at the boundary between the Virgin River and Lloyd domains. Most basement rocks to the western Athabasca Basin were subjected to multiple deformational and metamorphic events. The Virgin River shear zone was subjected to multiple displacement episodes under ductile, brittle-ductile, and brittle conditions. Brittle reactivation of the Virgin River shear zone, along the Dufferin Lake Fault, played a role in concentrating uranium at the basal unconformity of the Athabasca Basin.

How this classification was reachedexpand
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.
