The advents of Zr-in-rutile thermometer and Ti-in-zircon thermometer have prompted wide applications to petrological problems as well as ongoing tests of its validity. Some studies have demonstrated that the metamorphic temperatures measured by the Zr-in-rutile thermometer are in good agreement with the results obtained by cation partition thermometers, suggesting that the Zr-in-rutile thermometers is capable of providing the peak metamorphic temperatures. By comparison of the different studies, it is realized that the lower temperatures from the Zr-in-rutile thermometry is possibly caused not only by the variations of TiO₂ or SiO₂ activity, pressure correction, element diffusivity and retrograde reaction in the presence of fluid, but also by different stages of mineral growth. Therefore, the petrographic paragenesis, mineral inclusions and trace elements, and U-Pb ages should be taken into account when applying the all thermometers to continental subduction-zone UHP metamorphic rocks.
