Abstract
The texture and chemical compositions of secondary Ca–Al silicates (prehnite, pumpellyite, epidote, and titanite) and of related minerals (chlorite, sericite, K‐feldspar, albite, Fe‐oxides, fluorite, and calcite) are used to discuss their formation conditions during interaction of Proterozoic granitic rocks from SE Sweden with hydrothermal fluids. The paragenetic sequence of the Ca–Al silicates is suggested to have been accomplished at ca. 200–350°C and was controlled by small‐scale variations in the chemistry of the hydrothermal fluids, such as a Ca 2+ /a H + ratio and f O2 and f CO2 . These variations in fluid chemistry occurred mostly in closed systems, which involved the redistribution of elements released from the alteration of the magmatic minerals, primarily plagioclase, biotite, and amphibole and inducing porosity modifications. Accordingly, results obtained in this study should have implications for the role of hydrothermal alterations on element redistribution in the continental crust and for suitability of granitic rocks as repositories for radioactive wastes.

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 it
