Diffusion Kinetics and Geological Applications of Elements in Minerals

As an essential geochemical behavior,diffusion of elements in solid minerals has an important effect on the preservation of trace elements and their isotopic systematics. Therefore,it is widely used to solve different geochemical kinetic problems. At present,studies on the element diffusion in solid minerals are mainly dependent on various experimental simulations; meanwhile theoretical prediction is becoming an important tool to obtain diffusion parameters of different elements in solid minerals. Contrasted with many foreign scholars,few of domestic scholars have paid attentions to this problem. In order to promote the researches on element diffusion in minerals in China,the authors summarized the significant achievements in this studying field in recent years,and also described the importance of element diffusion and its geological applications in this paper.
