Regional characterization of mafic-ultramafic intrusions in the Oxford-Stull and Uchi domains, Superior Province, Ontario
Bibliographic record
Abstract
The mafic-dominated Big Mac, Fishtrap Lake, Highbank Lake, and Oxtoby Lake, the ultramafic-dominated Max, and the mafic-ultramafic Wabassi Main intrusions in the Oxford-Stull and Uchi domains of the Superior Province show significant potential for Fe-Ti-V-(P), Ni-Cu-(PGE), and/or Cr-(PGE) mineralization. The broadly layered Big Mac intrusion appears to have crystallized from an evolved high Fe-Ti basaltic parental magma that was injected from a feeder conduit below the northern part of the intrusion. The Fishtrap Lake and Highbank Lake intrusions represent parts of a large layered mafic-dominated igneous complex that formed from the injection of several pulses of basaltic magma. The genetically associated Max and Wabassi Main intrusions have crystallized from more primitive, basaltic parental magmas that were injected from a feeder conduit below the northwestern part of the Wabassi Main layered intrusion. In this magmatic system, the Max intrusion represents a magmatic conduit. The Oxtoby Lake intrusion appears to have crystallized from a differentiated basaltic parental magma and may represent an isolated intrusion.
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.
