Mantle lithosphere structure beneath southeast Baffin Island, Nunavut from teleseismic studies
Bibliographic record
Abstract
Earthquakes recorded at the Canadian National Seismic Network station FRB at Iqaluit, Nunavut between 1993 and 2009 were analyzed using receiver-function and SKS-splitting techniques in order to determine seismic discontinuities and anisotropy beneath the station. Discontinuities typically represent strong, localized changes in rock properties and therefore can indicate the presence of mul-tiple or dipping layers if these layers are regionally continuous. Both methods produce consistent results. Several stacked layers are interpreted to dip at approximately 15° to the northeast beneath station FRB at depths between 50 km and 150 km. The layers are defined primarily by their anisotropic characteristics that typically represent different rock fabrics. Geochemical evidence from kimberlite xenocrysts located 125 km to the northeast suggests that the layers are partly composed of harzburgite. Surface geological models suggest that the layers represent underthrusted or subducted parts of the Sugluk or Meta Incognita microcontinent blocks. A Moho depth of 43 km is estimated beneath station FRB.

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; both teacher heads agree on what is shown here.
