Abstract: Studying the diffusion characteristics and closure temperature of He in the surface and deep earth minerals is of great significance for understanding the information of earthquake precursors and tectonic activity. It is also important for understanding the process and law of mineralization. The article summarizes research results of the diffusion characteristics of He in some typical minerals. They mainly include: ① The diffusion of He diffusion in zircon; ② The diffusion of He in apatite; ③ The diffusion of He in quartz and coesite; ④ The diffusion of He in carbonate; ⑤ The diffusion of He in hydrated minerals such as amphibole. In order to analyze the relationship between the diffusion and escaping behavior of He from minerals and the anomaly of He concentration in the process of seismicity, the future research direction is proposed.
