'Ottawa-Bonnechere graben and Grenville Front in
Bibliographic record
Abstract
Reconnaissance using Seismic Techniques (COCRUST) conducted a major long-range seismic refraction and wide-angle reflection experiment across the Grenville province of the Canadian Shield. Three seismic lines each approxi-mately 300 km in length were located (i) along the Ottawa-Bonnechere graben, (ii) perpendicular to the graben and (iii) perpendicular to the Crenville Front. Geological evidence indicates that the graben may have originated from a failed arm of the St Lawrence rift system, and the Grenville Front marks the boundary between the Grenville province and the much older Superior province. Other geological features of the Grenville province that were traversed by the profiles were the Central Metasedimentary belt, and the Central Gneiss belt. Analysis of the data involved conventional travel-time procedures coupled with the use of synthetic seismogram analysis using programs that were written to handle laterally heterogeneous structures. Results from the survey indicate a variation in near surface seismic velocity at Pennsylvania State U niversity on M arch 5, 2016

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.
