会议简介
地质历史发生了众多快速和极端的增温事件，称之为极热事件。这类事件的主要特征是启动迅速（1-100000 kyr）和全球快速变暖（>2-4℃），同时常伴随气候、生物以及碳、水循环的剧烈扰动，总持续时间不超过几百万年。极热事件为研究人类世全球变暖提供了重要的地质参照，因而成为当前地球系统科学领域的研究热点。
中生代至古近纪是地球历史重要的气候演变期，期间发生了一系列典型的极热事件，包括但不限于二叠纪/三叠纪之交事件（PTB）、三叠纪/侏罗纪之交事件（TJB）、托阿尔阶大洋缺氧事件（TOAE）、白垩纪大洋缺氧事件（OAE1a，OAE2）以及古新世-始新世极热事件（PETM）。
联合国教科文组织国际地球科学计划IGCP739（2021-2025）聚焦于中生代-古近纪期间极热事件的触发机制及其相关的环境和生物响应。项目执行期间，已经取得了一系列重要成果。为进一步加深对极热事件的理解，分享最新研究进展，促进不同学科之间的交流，兹定于2025年8月16-18日于南京大学举办“国际中生代-古近纪极热事件学术研讨会暨第五次IGCP739学术年会”，并于8月19-26日围绕“极热事件环境响应”于我国藏南地区组织会后野外地质考察。
本次会议致力于打造跨学科国际对话平台，推动极热事件研究的学术共识构建。欢迎广大学者分享和交流您的原创发现，主题包括（但不限于）基础沉积学、地层学、地球化学、古气候学和古生物学，以及深时数据同化研究和区域或全球尺度的古气候地球系统模拟。

Invitation
Numerous rapid and extreme warming events, termed hyperthermal events, have punctuated Earth's geological history. These events are characterized by abrupt initiation (spanning 10⁴–10⁵ years) and accelerated global warming (>2–4°C), typically accompanied by severe perturbations in climate systems,biospheree, and carbonwaterr cycles, with total durations not exceeding several million years. Serving as crucial geological analogues for understanding Anthropocene global warming, hyperthermal events have become a research focus in Earth system science.
The Mesozoic to Paleogene represents a critical period of climatic evolution, during which a series of characteristic hyperthermal events occurred, including but not limited to: the Permian/Triassic boundary event (PTB), Triassic/Jurassic boundary event (TJB), Toarcian Oceanic Anoxic Event (TOAE), Cretaceous Oceanic Anoxic Events (OAE1a, OAE2), and Paleocene-Eocene Thermal Maximum (PETM).
UNESCOO's International Geoscience Programme IGCP-739 (2021-2025) focuses on deciphering the triggering mechanisms of Mesozoic-Paleogene hyperthermal events and their associated environmental/biological responses. Significant progress has been achieved during the project implementation. To advance understanding of hyperthermal events, disseminate recent findings, and foster interdisciplinary collaboration, the "International Symposium on Mesozoic-Paleogene Hyperthermal Events & 5th IGCP-739 Annual Meeting" will be convened at Nanjing University from August 16-18, 2025. This will be followed by a post-conference field excursion (August 19-26) in southern Tibet focusing on "Environmental Responses to Hyperthermal Events".
This conference aims to establish an interdisciplinary international platform for developing academic consensus on hyperthermal event research. Scholars are cordially invited to present original researchacrosss thematic areas including (but not limited to):fundamentall sedimentology, stratigraphy,geochemistryy, paleoclimatology, and paleobiology; deeptimee data assimilation studies; and regional/global-scale paleoclimate Earth system modeling.
