摘要
成矿年代的确认是现代矿床研究的热点,同位素测年法是通过具有天然放射性同位素的衰变规律精确测定矿物或岩石中放射性母体同位素和不断生成的稳定子体同位素之比来计算该矿物或岩石的地质年龄。在成矿年代研究中,同位素体系测年法越来越重要。从实验技术、理论研究等方面对常用的几种精度较高的同位素测年方法予以简要总结和介绍,主要包括U-Pb法、Ar-Ar法、Rb-Sr法、Sm-Nd法、Re-Os法等同位素测年方法,找出其中的优缺点。
The confirmation ofmetallogenic age is the focus of modem deposit research. Based on the decay pattem of natural radioactive isotopes, isotope dating can get the age of rock or mineral by calculating the ratio between radioactive parent isotopes and the constant production of stable isotopes in rock or mineral. The importance of isotopic dating method in the study of metallogenic age is increasing gradually. In this paper, we summarize several commonly methods of isotopic dating in view of theory and experimental techniques. We analyze advantages and disadvantages of isotope dating such as U-Pb, Ar-Ar, Rb-Sr, Sm-Nd, Re-Os.
