Magnetic phases in hemo‐ilmenite: Insight from low‐velocity and high‐field Mössbauer spectroscopy
Bibliographic record
Abstract
We have studied natural samples of hemo‐ilmenite (ilmenite with hematite exsolution lamellae) by use of Mössbauer spectroscopy. The samples are from the Allard Lake intrusion in Quebec. The stoichiometric compositions of the ilmenite host and the hematite lamellae are approximately Fe2+0.84Mg2+0.14Ti4+0.98Fe3+0.04O3 and Fe2+0.17Mg2+0.01Ti4+0.18Fe3+1.64O3, respectively. From low‐velocity Mössbauer measurements, the Fe2+ and Fe3+ components of the Fe2+‐substituted hematite and Fe3+‐substituted ilmenite, formed by incomplete exsolution of hematite and ilmenite, have been suggested identified. High‐field Mössbauer measurements, obtained at low‐temperature, indicate the presence of a minor ferrimagnetic component.

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.
