中文摘要：

扩散作用作为元素重要的地球化学行为，对矿物内部的微量元素及同位素信息有着重要影响，被越来越多地应用于解决地球化学动力学方面的问题。目前，对矿物中元素扩散行为的研究以实验模拟扩散过程的方法为主，同时理论预测的方法也逐渐成为获取扩散数据的一种重要手段。关于这一领域的研究，国外学者所做的工作较多，而我国开展的相关研究还非常少。为了促进国内在固体矿物中元素扩散动力学方面的研究及应用，本文对这一领域的研究现状及方法进行了归纳，并对扩散作用的研究意义与地质应用等做了阐述。

英文摘要：

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 geochemi- cal kinetie problems. At present, studies on the element diffusiot~ in solid minerals are mainly dependent on various experimental simulations; meanwhile theoretical prediction is becoming an important tool to obtain diffusion parame- ters 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.
