North Atlantic spreading axes terminate in the continental cul-de-sacs of Baffin Bay and the Laptev Sea
Bibliographic record
Abstract
In conventional plate-tectonic models, an independent Greenland plate is supposed to have drifted in the Paleogene along a transform fault through Nares Strait that links the two branches of the North Atlantic spreading system. However, this postulated structure — widely known as the Wegener Fault — cannot be detected by any means in the southern part of the strait. The mapped geology flanking this part of the strait is identical, with no evidence whatsoever of any strike-slip displacement or compressional deformation, and geophysical data provide no support for the existence of such tectonism offshore. We analyse the serious drawback of having a major transform located within a Precambrian crustal block stable since the Paleozoic and emphasize that the extinct Labrador – Baffin Bay spreading axis is but a mirror image of the active North Atlantic – Gakkel Ridge that terminates in a continental cul-de-sac in the Laptev Sea. We conclude that, in the Baffin Bay – Nares Strait region, there is only one plate (North American) and that the extension required to absorb Labrador – Baffin Bay spreading is to be found in structures within the Canadian Arctic Islands.

How this classification was reachedexpand
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.
