The duration of a magma chamber is of great significance for understanding the stability of the magma chamber and evaluating the active degree of active volcanoes. The element diffusion chronometry uses minerals with element concentration gradients as timers. Since the diffusion and reequilibrium process of elements in minerals conform to Fick's second law which is related to time， the time scale of the magmatic process can be defined to indicate the duration of a magma chamber. This method has been widely used in different minerals in volcanic rocks， such as Fe-Mg element diffusion in olivine and pyroxene， Mg element diffusion in plagioclase， Ti element diffusion in quartz and Li element diffusion in zircon， etc. These methods can record magma processes for only a few hours to millions of years. In the future， with the continuous development of in situ analysis and testing technology， the increase in the availability and accuracy of diffusion coefficients related to magmatism， and the improvement of the diffusion model， the development of element diffusion chronology in minerals will be greatly promoted.
