Calcium isotopes and aluminum-driven chemistry decipher fluorite mineralization in hydrothermal systemsCalcium isotopes and aluminum-driven chemistry decipher fluorite mineralization in hydrothermal systems

The data include comprehensive analytical data and methodological details supporting the research on fluorite mineralization mechanisms. These materials feature Figures S1 (geological maps of Chinese fluorite deposits), S2 (aluminous mineral assemblages), and S3 (Nd-Sr isotope correlation). The Supplementary Methods outline the precise protocols for Ca, H-O, Sr, Sm-Nd isotope analyses, trace/REE element determinations, and fluid inclusion microthermometry. Tables S1−S15 present global fluorite deposit characteristics (S1), isotopic compositions (S2−S4), trace/REE element concentrations (S5), extensive thermodynamic modeling of fluorite solubility under varying chemical systems (e.g., HCl, AlCl3, NaCl, CaCl2; S6−S11), and multicomponent system simulations (S13−S14), fluid inclusion results (S14), and fluid inclusion chemistry (S15).
