自第七届全国同位素地质年代学和同位素地球化学学术讨论会召开以来 ,已经过去四年。在这期间 ,我国同位素地质年代学和同位素地球化学研究取得了许多新的重要进展 ,获得了一系列重要成果 ,特别是SHRIMP_Ⅱ锆石微区定年技术和LA_MC_ICP_MS分析技术为我国同位素地质年代学和同位 It has been four years since the Seventh National Symposium on Isotope Geochronology and Isotope Geochemistry. During this period, many important new progresses have been made in isotope geochronology and isotope geochemistry in China. A series of important achievements have been obtained. In particular, the SHRIMP_Ⅱ zircon microdomains dating technique and LA_MC_ICP_MS analysis technique have been used in China’s isotope geochronology and isotope geochronology
