The anomaly signature of these features on the aeromagnetic data appears to range between 5 and 20 nT in amplitude. These anomalies are recognized by narrow vertical disturbance zones on the 2-D seismic profiles. We believe these lineaments are dike-like igneous bodies and refer to them as the Buffalo Creek dike field. Forward magnetic modeling indicates the depth of the dikes to be more than 200 m, and they are intruded into Western Canadian sedimentary basin strata. The magnetic model and seismic evidence suggest that the intrusion could have been produced at any time in the interval from the Frasnian to the Aptian. The proximity of the Buffalo Creek dike field to the Birch Mountain field may suggest that they could have identical origin and be related to subduction of the Farallon plate under the west coast of the North American plate.

How this classification was reachedexpand
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.
