Field relationships indicating cumulate intermingling at the Wrede Creek and Lunar Creek Alaskan-type ultramafic-mafic intrusions, north-central British Columbia
Bibliographic record
Abstract
Convergent margin-related magmatic deposits hosted by ultramafic-mafic intrusions are becoming an increasingly important global resource of Ni-Cu-PGE. In the northern Canadian Cordillera, a sub-class of ultramafic-mafic intrusions, known as the Alaskan-type intrusions, are hosted within the accreted arc terranes of the North American continental margin. These intrusions have long been recognized for their chromite-associated PGE mineralization potential. However, their potential to host significant Ni-Cu-PGE sulfide mineralization and to be used in efforts to reduce greenhouse gas emissions through permanent carbon mineralization is becoming increasingly studied. This report describes the main lithologies and field relationships observed at the Wrede Creek and Lunar Creek Alaskan-type intrusions in British Columbia during recent fieldwork.
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.
