Nouveau regard sur l'architecture de la Plate-forme du Saint-Laurent et des Appalaches du sud du Québec par le retraitement des profils de sismique réflexion M-2001, M-2002 et M-2003
Bibliographic record
Abstract
This study presents the results of the reprocessmg and geological reinterpretation of three regional seismic reflection lines acquired by the Ministère des Ressources naturelles du Québec in 1978. The three lines (M-2001, M-2002 and M-2003), which represent 280 km of data, cross the Chambly-Fortierville syncline and provide images of the St. Lawrence Platform and the Appalachian fold and thrust belt in southern Quebec. Line M-2001, the longest profile, extends across the full width of the southern Quebec Appalachians. Data reprocessing has improved the quality of the seismic sections by enhancing coherent reflection events and attenuating reflection noise. Time migration further improves the structural images. The seismic interpretations provide new information on subsurface geology, including the recognition of complex structural patterns in foreland and platform units, the presence of triangle zones at the structural front, and the geometry of thrust slices of platform units and Appalachian thrust nappes. The M-2001 line also provides images of the interna! Humber zone, including back-thrust faults on the flanks of Notre-Dame Mountains Anticlinorium and mega thrust wedges, most probably involving Grenvillian basement, within the core of the anticlinorium. The reprocessing and reinterpretation of existing seismic reflection profiles provides an efficient and economical research activity, allowing for improved evaluations of geological models and assessments of hydrocarbon potential.

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.
