Proterozoic structural highs beneath the Mackenzie Mountains, northwest Canada, discovered with filtered potential field and seismic data
Bibliographic record
Abstract
A linear belt of Mesoproterozoic (ca. 1.6 Ga) structural highs, some with more than 6-7 km of subsurface relief, underlies the Mackenzie Mountains in northwestern Canada over a distance of at least 1000 km from southeast to northwest. The trend is visible on isostatic gravity data that were bandpass filtered to wavelengths appropriate for intracrustal features, and on seismic reflection profiles that have images of buried Proterozoic anticlines associated with the gravity highs. The combination of filtered potential field data tied to seismic images of subsurface structure in key areas provides a powerful method to map intracrustal structures at long distances away from cross-sectional profiles. Resume Une bande lineaire de hauts structuraux du Proterozoique moyen (ca. 1,6 Ga) est visible sous les monts Mackensie, dans le nord-ouest du Canada, et s'etale sur une distance d'au moins 1 000 km, selon une direction sud-est-nord-ouest; certains de ces hauts depassant les six a sept km de denivele en subsurface. Cette bande lineaire ressort sur le trace des donnees gravimetriques isostatique filtrees aux longueurs d'onde correspondant aux elements intracrustaux, ainsi que sur les profils de reflexion sismique qui donnent des images d'anticlinaux proterozoiques souterrains associes aux hauts gravime-triques. La combinaison de donnees filtrees de champs de potentiel, et d'images sismiques des structures de subsurface en des endroits cle constitue une methode tres puissante permettant de dresser la carte de structures intracrustales situees a de grandes distance des profils de coupes.

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.
