At present, a large number of experimental studies have obtained some behaviors and thermodynamic data of Zr minerals in hydrothermal solutions. However, due to the limited number of researchers using complex hydrolysis method and the limited scope of research, and the lack of data, the accuracy of the data cannot be confirmed. Therefore, in order to comprehensively understand the fluid migration ability of Zr and verify previous experimental data, this study uses a combination of fluoride rich complex hydrolysis and thermodynamic simulation calculation to study the fluid activity of Zr. Through high-temperature and high-pressure experiments, the problem of fluoride rich zirconium complex hydrolysis behavior in hydrothermal systems is explored. The experimental results showed that the hydrolysis rate gradually increased with the increase of temperature between 150˚C~500˚C. When the temperature reached 500˚C, the hydrolysis rate had already reached over 90%, and the cumulative hydrolysis equilibrium constant of Zr-F complex under experimental conditions was obtained. This experiment can help explain why the occurrence of F-rich fluids may be the reason for the abnormally low Zr/Hf content of zircon in pegmatite. The experimental results can also provide assistance in verifying the hydrolysis data of Zr-F complexes. %K 氟锆络合物, %K 水解反应, %K 热液体系
