摘　　要：2018年6月21日,国际地科联全票通过批准寒武系第三统为苗岭统,第5阶为乌溜阶的全球标准层型及点位(GSSP)的建议,落户在中国贵州八郎,这是我国获得的第11个金钉子,使我国成为拥有金钉子最多的国家。由贵州大学赵元龙为首的由贵州大学及中科院南京古生物研究所等单位组成的国际研究团队,历时35年,通过三叶虫、疑源类地层、层序地层,无机及有机地球化学等多学科综合研究,经过了激烈的多国竞争而获得,成为全球同期地层对比中心。On June 21,2018,the International Union of Geo-Science(IUGS)unanimously ratified the proposal that Cambrian Miaolingian Series-Wuiliun Stage Boundary located in Balang,Guizhou was Global Stratotype Section and Point(GSSP),confirming Miaolingian Series as the Cambrian Series 3 and Wuliuan stage as the Cambrian stage 5.It was the 11th GSSP of China,making China the country with the most GSSP.The research project was carried out by an international research team led by Yuanlong Zhao,composed of researchers from Guizhou University and Nanjing Institute of Geology and Palaeontology,Chinese Academy of Sciences and so on.After 35 years’laborious work involved in stratigraphic correlation among Trilobites,Acritarchs and multidisciplinary work including Organic chemistry Inorganic chemistry,the whole research project has been successfully completed by the research team.After intensive competition among countries,the Cambrian Miaolingian Series-Wuiliun Stage Boundary proposed by the research team finally gained the unanimous votes to be the Worldwide Stratigraphic correlation center during the same period.helping China earn the fame in geochronological field.
