Clay and Magnetite Formation at Yellowknife Bay, Mars
Bibliographic record
Abstract
The Curiosity Rover of Mars Science Laboratory, has analysed a set of mudstones at the Yellowknife Bay locality of Gale Crater, that record a history of deposition within a habitable, fluvio-lacustrine environment followed by low T alteration. The composition and mineralogical information preserved in the sediments provide a unique opportunity to determine the nature of the environment. In particular we aim to constrain the mineral reactions, Water/Rock ratios, pH, and redox associated with the saponite-, magnetite-bearing assemblage identified by CheMin in the Sheepbed mudstone and compare to martian clay compositions in the Lafayette nakhlite. The presence of cm-scale ridges, which have a more Mg-rich compo-sition than the surrounding mudstone, suggest that the diagenetic fluids changed in composition as alteration progressed. An important factor in our alteration model is the presence of amorphous material and olivine, together with secondary phases in the drilled samples.

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.
