Bibliographic record
Abstract
Table S1. Compositional Data. (S1a) APXS compositional data for targets from sol 3078 to sol 4028; (S1b) Percentage change relative to mean Mount Sharp group (pre-Marker Band Valley). All data reported as wt. % except Ni, Zn, Br (ppm). Error = 2σ statistical precision error. Table S2. Average calculations. (S2a) Summary of results. (S2b) Contigo interdune lenses, Mirador fm. (S2c) Mount Sharp group (sols 722-3532). (S2d) Clay Sulfate Transition (CST) (sols 3085-3712). (S2e) Chenapau mbr, Mirador fm above Amapari Marker Band. (S2f), Contigo mbr in Marker Band Valley and Catrimani mbr in Marker Band Valley; both Mirador fm, below Amapari Marker Band Valley. Table S3. Variance analysis. (S3a) Summary of results. (S3b). Calculations, including: Kruskal-Wallis test; Welch’s test; Levene’s Test; Games Howell post-hoc test; Q-test results. (S3c) List of included targets. Table S4. Two- and three-end member Iterative modeling calculations. (S4a) Summary of results. (S4b) Three-end member model: Mirador fm (pre-Marker Band Valley) (MBV) plus Gale sands (active) plus dust. (S4c) Three-end member model: Clay Sulfate Transition (CST) (excluding MBV) plus Gale sands (active) plus dust. (S4d) Two-end member model: Mirador fm (pre-MBV) plus Naukluft Plateau (Stimson fm). (S4e) Two-end member model: Mirador fm (pre-MBV) plus Emerson Plateau (Stimson fm). (S4f) Two-end member model: CST (excluding MBV) plus Naukluft Plateau (Stimson fm). (S4g) Two-end member model: CST (pre-MBV) plus Emerson Plateau (Stimson fm).
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.
