Introduction to special issue of <i>Canadian Journal of Earth Sciences</i>: The Trans-Hudson Orogen Transect of Lithoprobe
Bibliographic record
Abstract
Dedication: Dr. John F. Lewry (19391999; see Saskatchewan Geological Survey 1999) dedicated his career to investigations of the SaskatchewanManitoba segment of the Trans-Hudson Orogen (THO), one of the principal Paleoproterozoic orogens associated with the assembly of Laurentia. Indeed, one can make a strong case that Lithoprobe's Trans-Hudson Orogen Transect (THOT) was designed to test the tectonic models proposed by John Lewry. He delineated the distinct tectonic provinces in the western part of the THO, predicted the presence of an Archean craton trapped within the THO, and recognized and interpreted the significance of the Pelican Thrust between the juvenile Paleoproterozoic volcanic arc complex of the western Flin Flon Domain and the Archean craton, now called the Sask craton. The research published in Lewry and Stauffer (1990), and many of his ideas, provided the framework for the design of the THOT geophysical and geological studies. John Lewry was co-leader of the THOT until he passed away in 1999 after a battle with cancer. This Special Issue of the Canadian Journal of Earth Sciences is dedicated to him.

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.
