Stratigraphy interpretation of north Atlantic conjugate margins
Bibliographic record
Abstract
ABSTRACT The recent multi-million barrel discoveries offshore Newfoundland (Flemish Pass) made by Statoil and partners has stimulated interest in the petroleum systems evaluation of the conjugate European and Canadian Atlantic margins. However, the North Atlantic conjugate margins lack a unified stratigraphic framework. CGG Robertson has, with industry support and the encouragement of the Irish, Canadian and Portuguese licensing authorities, undertaken a petroleum geological review of the Neogene to Palaeozoic succession of the North Atlantic margins. Multiple bioevents have been identified, based on micropalaeontological, nannopalaeontological and palynological studies, associated with the re-interpretation of old reports, revisiting archived slides and analysing new samples from Canada, Ireland and Portugal. These robust bioevents allow detection, quantification and differentiation of hiatal surfaces across the conjugate margin. The identification of the geographical extent and relationships between the pre-rift, syn-rift and post-rift successions has provided exciting new insights into the rifting history of the North Atlantic region and has implications for future deepwater exploration of the Tertiary and Mesozoic succession.

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.
