Method for determining the temperature at which fluid inclusions in a purple fluorite change from a plurality of phases to a single phase
By improving the transparency of purple fluorite samples and employing a multiple quantitative heating-cooling method, the problem of inaccurate temperature measurement in infrared microscopy observation was solved, enabling more accurate determination of phase transition temperatures and inference of the thermodynamic conditions of uranium deposit ore-forming fluids.

AI Technical Summary
Existing technologies, when using infrared microscopes to observe fluid inclusions in purple fluorite, suffer from inaccurate determination of phase transition temperatures due to the infrared heating effect, making it difficult to accurately reflect the thermodynamic conditions of the ore-forming fluids.
By increasing the transparency of the purple fluorite sample to reveal fluid inclusions, a multiple quantitative heating-cooling method was used to determine the temperature at which the fluid inclusions transitioned from multiple phases to a single phase, avoiding infrared heating and improving the accuracy of temperature measurement.
This improves the accuracy of phase transition temperatures, truly reflects the thermodynamic conditions of ore-forming fluids, and helps to infer the evolution and formation conditions of ore-forming fluids in uranium deposits.
