Multiphased syn-rift segmentation on the SW Iberian margin
Bibliographic record
Abstract
The Alentejo Basin in palaeogeographic proximity to neighbouring provinces such as the West Tethys, North Africa and the conjugate South Newfoundland margin is a key area to clarify some of the unclear aspects of the syn-rift evolution and the geometry of non-volcanic rift margins. The analysis of 2D seismic surveys, boreholes and dredge data allow recognizing three discrete Syn-Rift phases and their correlated structural sectors across the SW Iberian margin, evidencing nearly continued subsidence from the Late Triassic to the Late Jurassic. Significant extension occurred during the Middle Jurassic, synchronous to extension between the North Africa-Nova Scotia conjugate. Late Jurassic subsidence at the distal margin, ultimately lead to seafloor spreading west of the Tagus Abyssal Plain is coeval to extension in Newfoundland. During continental extension of the SW Iberian margin major subsiding sectors migrated westwards towards the locus of continental breakup, which is interpreted to have occurred by the latest Jurassic-earliest Cretaceous.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
