Seismic stratigraphy of the Paleozoic succession and subsurface mapping of the Macasty Formation in Jupiter River area, Anticosti Island, Quebec, Canada
Bibliographic record
Abstract
This study presents the methodology used for the processing and interpretation of seismic reflection data in the Jupiter River area of the Anticosti Island. The seismic characteristics of the rock formations investigated are described and time-structure maps of the tops of the Mingan and Macasty formations are presented as well as a map documenting the thickness variation of the Macasty Formation. Subsurface maps present time and thickness estimations that take into account exploration wells and regional seismic data, yet are limited by the spatial distribution and vertical resolution of seismic data. Time-structure maps of the top Mingan and Macasty formations portray a shallow and a deep domain delimited by the Jupiter Fault which probably corresponds to a composite structure with several 'en échelon' fault segments. The thickness map of the Macasty Formation reveals thicker accumulation and/or preservation of this unit within a NW-SE fairway bounded to the northeast by the Jupiter Fault and to the southwest by the Ruisseau Jean IV and the Rivière du Brick faults. North of the Jupiter Fault the Macasty Formation is considerably thinner.

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.
