摘要: 研究氦(He)在地表和地球深部矿物中的扩散特征与封闭温度, 对了解地震前兆信息和构造活动有重要意义, 对了解成矿过程及规律也有重要价值。 本文综述了He在石英等典型矿物中的扩散特征研究成果, 主要包括: ① He在锆石中的扩散; ② He在磷灰石中的扩散; ③ He在石英和柯石英中的扩散; ④ He在碳酸盐中的扩散; ⑤ He在角闪石等含水矿物中的扩散, 分析了He从矿物中扩散逃逸行为与地震活动过程中He浓度异常的关系, 对未来的研究方向提出了展望。

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.

Key words: Earthquake precursors, Helium diffusion, Mineral physics, Thermochronology
