火山灰已被广泛用作唯一的独立标志层，用于定年和同步古环境和考古记录。在这里，我们报告了一系列的关键广泛的晚更新世至全新世火山灰层位从中国南部的湖泊序列，有显着的潜力，从东亚的年代和同步的古环境记录。通过这些广泛分布的火山岩，包括对新仙女木和全新世中期气候事件的综合研究，可以实现热带菲律宾，中国大陆和中纬度日本的平移古气候，古环境和考古学相关性。此外，我们还建立了1991年前皮纳图博火山喷发的精确年龄，并根据湖泊序列年龄模型确定了晚更新世吕宋火山喷发的年龄，这将有助于未来研究热带火山喷发对气候变化的影响。我们的研究结果突出了人口稠密的东亚地区周围的火山灾害，并为解决该地区快速气候事件同步中的测年不确定性提供了解决方案。
Volcanic ash has been widely used as unique independent marker horizons for dating and synchronizing paleoenvironments and archeological records. Here, we report a series of key widespread late Pleistocene to Holocene tephras horizons from a lake sequence in southern China that have significant potential for dating and synchronizing paleoenvironmental records from East Asia. Translatitudinal paleoclimatological, paleoenvironmental, and archeological correlations from the tropical Philippines, mainland China, and midlatitude Japan are achievable through these extensively distributed tephras, including synthetic studies of the Younger Dryas and mid‐Holocene climate events. Additionally, we establish refined ages for four pre‐1991 Pinatubo eruptions and date three late Pleistocene Luzon eruptions based on the lake sequence age model, which will facilitate future studies of tropical volcanic eruptions’ forcing of climate change. Our results highlight the volcanic hazards around densely populated East Asia, and bring solutions to resolving dating uncertainty in the synchronization of rapid climate events across the region.
