Teleseismic investigations of the lithosphere beneath central Baffin Island, Nunavut
Bibliographic record
Abstract
From summer 2000 to summer 2002, five self-contained seismic stations were established and operated on central Baffin Island to study the lithospheric structure across the Proterozoic-Archean boundary, the northern margin of Trans-Hudson Orogen. Crustal thickness estimates decrease steadily from 40 (±2) km in the southeast to 37 (±2) km beneath the Archean block in the northwest. Prominent southward-dipping mantle discontinuities occur beneath the southeasternmost stations at about 100 and 140 km depth, defining a layer of increased seismic velocity. Crustal discontinuities occur at 2 and 15 km depths beneath these stations. Two layers with differing anisotropic properties are also indicated in the south from observed azimuthal variations in the splitting of teleseismic SKS-waves: probable axes of anisotropy strike at 82° and 41°. In the north, neither clear discontinuities nor anisotropy are observed, suggesting a heterogeneous lithosphere.

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.
