Heating Saponite, Serpentine, and a Carbonaceous Chondrite Spectral Analogue Under Vacuum to Track the Spectral Variability of the 2.7 µm Band.
Bibliographic record
Abstract
The scientific significance of carbonaceous chondrites has been established as windows into our early Solar System [1]. The presence of phyllosilicates in CM2 carbonaceous chondrites indicates a history of aqueous alteration [2, 3]. Carbonaceous chondrites (CCs) exhibit spectral similarities to several C-complex asteroids, which may act as parent bodies [4, 5]. Several CCs (and therefore their parent body asteroids) have undergone thermal alteration following aqueous alteration [6, 7]. Here we present the reflectance spectra of heated saponite, serpentine, and a spectral analogue created at the Centre for Terrestrial and Planetary Exploration (C-TAPE) laboratory at the University of Winnipeg, Canada. The intent is to understand how thermal metamorphism affects their spectroscopic properties.

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.
