Abstract
Fluid inclusions provide a wealth of information on the compositions, temperatures, and other properties of fluids that form mineral deposits. Fluid inclusions representative of aqueous-hydrothermal ore-forming fluids have been studied extensively over many years, and our understanding of their properties is comprehensive. But in recent years, evidence has been mounting for widespread occurrence of novel and unexpected types of fluid inclusions. These fluids are composed of molten alkali-calcic chloride, sulfate, and carbonate components, and they contain little to no H 2 O. Their physical and chemical properties are only starting to be explored, but evidence for their capacity to mobilize certain metals, and their participation in crustal ore-forming processes, is growing. The objectives of this review are to showcase these novel solutions and to discuss their origins and roles in forming mineral deposits. ▪ Fluid inclusions in minerals reveal widespread occurrence of natural molten salts. ▪ Evidence for molten salts, composed of chloride, sulfate, and carbonate components, is reported in numerous ore deposits. ▪ Molten salts are low-viscosity fluids, highly chemically reactive, and capable of transporting high concentrations of critical metals. ▪ Molten salts represent a novel and unexpected type of crustal ore-forming fluid.

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
