Abstract
The thermal conductivities of the main silicate minerals are well known and vary within a rather large range of about 1.6–7.7 W m-1 K-1 (Horai and Simmons, 1969; Diment and Pratt, 1988). The lowest and largest conductivity values are those of plagioclase and quartz, respectively. In principle, it is possible to calculate the thermal conductivity of a rock from knowledge of its mineral phases and their proportions. The procedure is discussed in a separate section below but is rarely implemented. Silicate minerals are anisotropic and belong to solid solutions with end-members that may have very different conductivities. An accurate prediction would thus require determination of the composition and orientation of each mineral phase. For heat flux measurements, furthermore, such determinations would need to be done over a representative rock volume and not at the scale of a petrological thin section. For this reason, thermal conductivity must be measured on each and every rock type encountered in a borehole. For regional thermal models, one may choose representative values for the dominant rock types, but one must pay attention to the level of approximation that is entailed.

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; both teacher heads agree on what is shown here.
