摘要:

(U—Th)/He定年技术是近年来快速发展起来的一种新的放射性同位素定年方法,已经在基础地质研究领域得到了广泛应用。在介绍(U—Th)/He定年方法技术原理的基础上,对此技术发展现状和地质应用研究成果做出简要总结,并对用该方法研究金属和非金属矿床成矿时代、研究金属矿床后期改造和矿床揭顶时代的可行性进行探讨。

关键词: (U—Th)/He, 同位素定年, 矿床年代学

Abstract:

(U—Th)/He dating method is a new radiogenic isotope dating method rapidly developed in recent years,which has been applied widely in the research field of basic geology.At first,we simply present the(U—Th)/He dating principle and summarize its technique development and application results in geological research.Furthermore,we discuss the feasibility of(U—Th)/He dating in determining the forming age of nonmetallic—metallic ore deposit,the succeeding alteration and unroofing age of metallic ore deposit

Key words: (U—Th)/He, Isotope dating, Ore deposit geochronolog
