Combined rigid/deformable plate tectonic reconstructions for the central Atlantic margins
Bibliographic record
Abstract
Oceanic crust and highly extended continental crust have very similar physical properties and for this reason, the exact location of the continent-ocean boundary (COB) along passive continental margins can be difficult to define. The effect of igneous intrusions and magmatic underplating on calculations of crustal thickness further complicates this issue. A number of geological and geophysical datasets such as magnetic isochron data have been employed to define new plate boundaries and infer the location of the COB. The Iberian and Newfoundland conjugate margins are zones where anomalously large amounts of crustal extension have occurred, and are difficult to reconstruct in a global context using plate tectonic models based on rigid plates. A self-consistent global, plate tectonic model is presented here that incorporates stretching factors, deformable plates and scales deformation for the Cenozoic and Mesozoic for the entire Atlantic margin. Restoration to pre-rift geometries has been achieved by removal of plate ‘overlap’ of the deformed regions in the reconstructions, and is consistent with estimated stretching factors derived from deep seismic crustal studies across the conjugate margins.

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; a candidate call from one teacher head, not a consensus.
