全球环境变化的研究已成为第四纪地质学中的热点,而高精度、高灵敏度测定年龄又是其中迫切需要解决的关键问题之一.本文介绍了目前国内外用热电离质谱(TIMS)铀系法对海洋珊瑚定年和Sr/Ca值的测定及对古环境研究的一些成果.最近我们也用MAT-262质谱仪对珊瑚进行过测试,取得了比较满意的结果.
The study of global environmental change has become a hot spot in Quaternary geology, and the determination of age with high precision and high sensitivity is one of the key problems that need to be solved urgently.This paper introduced the current domestic and international thermal ionization mass spectrometry (TIMS) uranium series Act on marine coral dating and Sr / Ca value determination and some of the results of paleoenvironmental studies recently we also used MAT-262 mass spectrometer coral tested and achieved satisfactory results.
