Recently, China has made significant new progress in research on ‘Golden Spikes’—officially known as Global Boundary Stratotype Sections and Points (GSSPs). A scientific team led by the Chinese Academy of Geological Sciences has successfully established a new Cambrian GSSP in South China, further strengthening the country’s influence in global stratigraphic correlation and division. GSSPs serve as the international ‘gold standard’ for defining and identifying boundaries between geological time units. Their establishment requires rigorous multidisciplinary evidence from stratigraphy, paleontology, geochemistry, and must gain broad consensus from the international scientific community. This newly ratified GSSP not only refines the timeline of early Cambrian biological evolution but also provides a crucial stratigraphic reference for studying the Cambrian Explosion—the rapid diversification of complex life forms. The findings have been published in a leading international geoscience journal and have drawn considerable attention from the global academic community. To date, China hosts 11 GSSPs, ranking among the highest globally, highlighting its growing scientific prowess and international standing in stratigraphy and paleontology.
近日，中国在“金钉子”（全球界线层型剖面和点位，GSSP）研究领域取得重要新进展。由中国地质科学院牵头的科研团队，在华南地区成功确立了一处新的寒武纪地层“金钉子”，标志着我国在全球地层划分与对比研究中的话语权进一步提升。“金钉子”是国际地层委员会为定义和识别全球不同地质年代界线而设立的“黄金标准”，其确立需经过严格的地层学、古生物学和地球化学等多学科论证，并获得国际同行广泛认可。此次新确立的“金钉子”不仅完善了寒武纪早期生物演化的时间框架，还为研究地球生命大爆发提供了关键地层依据。该成果已发表于国际权威地学期刊，受到国际学术界高度关注。截至目前，中国已拥有11枚“金钉子”，数量位居全球前列，彰显了我国在地层学和古生物学领域的科研实力与国际影响力。
