Structure and rifting evolution of the northern Newfoundland Basin from Erable multichannel seismic reflection profiles across the southeastern margin of Flemish Cap
Bibliographic record
Abstract
We present the results from processing and interpreting five lines from the 1992 Erable \nmultichannel seismic reflection experiment extending from the southeastern margin of Flemish \nCap into the northern Newfoundland Basin. These profiles reveal significant along strike \nvariations in the rifting styles experienced by Flemish Cap. In the southwest, a 100-km-wide \ntransition zone is identified between thinned continental crust and thin oceanic crust. Similar \nto the conjugate Galicia Bank and Iberian margins, this transition zone contains a section \nof deep basement adjacent to a series of shallower ridges and is interpreted as exhumed \nserpentinized mantle. Along strike towards the northeast, this transition zone pinches out \ncompletely within 100 km and is replaced by thin oceanic crust directly adjacent to thinned \ncontinental crust. By interpreting nearby seismic profiles and profiles on the conjugate margins \nusing the same classification criteria, we construct regional maps of the distribution of crustal \ndomains on both sides of the North Atlantic. These maps reveal significant variations in \nrifting style on the conjugate margins and along strike of each margin and also highlight \nthe role of ancient transfer zones in compartmentalizing these rifting variations into four \ndistinct regions. We propose that the limited localization of shallow topographically high \nserpentinized peridotite ridges on the Newfoundland-Iberia and Flemish Cap-Galicia Bank \nconjugate margins, was directly related to an increase in the rate of extension following \nthe separation of Flemish Cap and Galicia Bank which exhumed deeper, less serpentinized \nmantle.

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.
