On the possibility of single‐domain/pseudo‐single‐domain magnetic particles existing in the lower crust of Mars: Source of the strong magnetic anomalies
Bibliographic record
Abstract
This paper shows that single‐domain or pseudo‐single‐domain (SD/PSD) magnetite grains can exist in the upper 30–45 km of the Martian crust. The upper ∼50 km of the Martian crust have likely formed by volcanic eruptions on a stagnant lithosphere. A given lava flow cools very rapidly at the surface but is then gradually heated up through burial heating as it is overlain by other successive flows. The thermal evolution models of a lava flow show that its temperature remains below the magnetic blocking temperatures of magnetite, 480–580°C, until it reaches ∼30–45 km depth. The highly magnetic SD/PSD magnetite grains can easily explain the strong magnetic anomalies of Mars; less than 1% by volume of magnetite particles is sufficient.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
