Quetico Fault in the Superior Province of the southern Canadian Shield / by Myra Carolyn Kennedy. --
Bibliographic record
Abstract
The Quetico fault is a major transcurrent fault in the \nsouthern Superior Province of the Canadian Shield. Along part of \nits length the fault forms the boundary between the \nWabigoon subprovinces. Dextral motion on the fault \nby dextral microfaults and appropriately asymmetrical quartz \nc-axis petrofabrics. \nThe fault comprises a zone of dynamically metamorphosed \nrocks - primarily mylonitic rocks with some cataclastic rocks and \npseudotachylite. A transition from predominantly ductile \ndeformation to brittle deformation occurred during the time the \nfault was active. \nThe ductile deformation of quartz within the fault zone \nis the result of crystal-plastic processes, \nprism planes in the a-direction and slip on \na-direction, accompanied by dynamic recovery and syntectonic \nrecrystallization. Feldspar grains are commonly deformed in a \nbrittle manner by fracture processes. Particulate flow appears \nto have made a significant contribution to deformation in the \nfault zone. \nThe harmonic mean of deformed grain axial-ratios and strain determinations by the all object-object separations method \nindicate that flattening strain is predominant within the fault \nzone. The magnetic susceptibility anisotropy ellipsoid is also \nflat-shaped and coaxial with the strain ellipsoids. The \ncharacteristics of microfaults and folds within the fault zone \nindicate that flattening may have been accompanied by or followed \nby shearing. The harmonic mean of deformed quartz grain axial \nratios yields a minimum strain estimate of 130% extension in X, \n58% extension in Y, and 71% shortening in the 1 direction.

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.
