ELECTROMAGNETIC IMAGES OF REGIONAL STRUCTURE IN THE SOUTHERN CANADIAN CORDILLERA
Bibliographic record
Abstract
transect investigations, magnetotelluric (MT) soundings were made at 160 sites providing unprecedented coverage from the Rockies to the west coast. Striking lateral varia-tion, which spatially correlates with the morphogeological belt boundaries, is apparent at periods sensing the lower crust (~10 s). For the Rockies, MT phases are around 35°, indicative of a moderately resistive (lOO's- 1000's!lm) North American Basement. Foreland belt phases are transitional and increase from 60 ° in the east to 70 ° in the west. Omineca and Coast belt phases are high (75°), implying a conductive (10-30 n·m) lower crust, whereas Intermontane belt phases are more than 10 ° lower (equiv-alent to ~150 n·m). The regional variation in conductiv-ity correlates to first order with surface heat flow changes along the profile and is also correlative with coincident seismic reflection sections in some aspects.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
