The crustal structure of the Southern Nain and Makkovik Provinces of Labrador deriverd from seismic refraction data.
Bibliographic record
Abstract
A refraction seismic profile was used to determine the crustal structure across the Nain/ Makkovik boundary, and to look for an offshore continuation of the Nain Plutonic Suite (NPS). Velocity models were developed from forward and inverse modeling of travel times. There are. In the Saglek block the crust has P-wave velocity 5.8 -6.9 km/s. Further south, upper crustal velocities iand the Poisson's ratio increase. This zone correlates with a gravity low interpreted as the NPS. The upper crustal velocities are compatible with the NPS. There is a lower crustal reflector under the NPS. In the Makkovik Province, upper crustal velocities are 5.9-6.2 km/s.. Moho is between 28 and 36 km. The variations may relate to Labrador Sea rifting.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
