Central Baffin Electromagnetic Experiment (CBEX), Phase 2
Bibliographic record
Abstract
As a part of the Central Baffin Multidisciplinary Project (a collaborative effort of theGeological Survey of Canada, The Canada-Nunuvut Geoscience Centre, and the Polar Continental Shelf Project), a 45 station, 500 km long regional-scale magnetotelluric profile was acquired. The profile crosses the northern margin of the Trans-Hudson Orogen and extends northward into the Archean Rae Craton. To the south, the profile crosses the Paleoproterozoic Piling Group. The primary goal of the experiment was to determine major geological boundaries by delineating regional electrical structures. Preliminary analysis shows that the conductive Astarte River Formation can be mapped and used as a proxy for the base of the Piling Group. Analysis has also revealed a high conductivity contrast between the Piling Group metasedimentary rocks and the northern Archean granite and gneissic complexes. Laboratory results indicate that the conductivity in the Astarte River Formation is due to the high content of interconnected graphite.

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.
