1. Invitation

The International Workshop on Mesozoic–Palaeogene Hyperthermal Events & Fifth IGCP 739 Workshop will be held on August 16–18, 2025 at Nanjing University, Jiangsu, China. The workshop is open to anyone from a university, research institute, or industry, and we cordially invite you to participate.

Nanjing is located in eastern China on the Yangtze River, approximately 300 kilometers west of Shanghai. It is the capital of Jiangsu Province. Historically, Nanjing is known as one of China’s ancient capitals, serving as “Ancient Capital of the Six Dynasties” and the “Capital of the Ten Dynasties”, including the early Ming dynasty and the Republic of China. It is recognized by China as a national central city and an important cultural and historical city and also designated as a core city for innovation and modernization in eastern China. Nanjing’s cultural appeal is evident in its renowned landmarks, such as the Sun Yat-sen Mausoleum, the Confucius Temple, the Nanjing City Wall, and the Ming Xiaoling Mausoleum, which attracts millions of visitors annually and showcases the city’s deep historical and architectural legacy.

A post-workshop field trip will be organized in conjunction, from August 19–26, in southern Tibet and across the Himalaya. Tibet is located on the Qinghai-Tibet Plateau, often referred to as the Roof of the World. It is an autonomous region and a key area within China, sharing borders with several countries including India, Nepal, and Bhutan. Lhasa, its capital, lies at the heart of Tibetan culture and spirituality. Historically, Tibet has been a significant cultural and religious hub, known for its unique blend of Tibetan Buddhism and traditional lifestyles. Recognized as a national ecological security barrier and an important cultural and historical region, Tibet also plays a crucial role as the Asian Water Tower, as the plateau is the source of many major rivers in Asia, including the Yangtze, Yellow, Mekong, and Brahmaputra rivers. Its cultural and natural appeal is evident in landmarks such as the Potala Palace, Jokhang Temple, Namtso Lake, and Mount Qomulama's northern base camp, which attract millions of visitors annually and highlight Tibet’s breathtaking landscapes and profound spiritual legacy.

The UNESCO International Geoscience Programme (IGCP) 739 focuses on the Mesozoic–Paleogene hyperthermal events recorded in the geological record. Notable examples include the Permian–Triassic Boundary Event, Carnian Pluvial Event, Triassic–Jurassic Boundary Event, the Jurassic and Cretaceous Oceanic Anoxic Events, and the Paleocene–Eocene Thermal Maximum. The IGCP 739 project aims to further enhance the international recognition and visibility of hyperthermal events, serving as an exceptional platform for fostering engaging discussions, promoting extensive collaboration, and facilitating new discoveries.

We welcome original findings, reviews, or reports on topics including (but not limited to) fundamental sedimentology, stratigraphy, geochemistry, palaeoclimatology and paleontology, as well as deep-time data assimilation studies and paleoclimate Earth system modelling at regional or global scales.

2. Preliminary Scientific Program Schedule

The workshop will include two days of scientific sessions (August 17–18, 2025), and an eight-day post-workshop field excursion to investigate the Mesozoic hyperthermals in the Tibetan Tethys (August 19–26, 2025). The preliminary plan for the field excursion is to view the regional geology in the Tibetan Himalaya, and especially the records of hyperthermals events preserved there. The field excursion aims to visit sections that record: 1) the Permian–Triassic Boundary Event (Selongxishan section), 2) the Carnian Pluvial Event (Tulong section), 3) the Triassic–Jurassic Boundary Event (Gemige Section), 4) the Toarcian Oceanic Anoxic Event (Nianduo section), 5) Cretaceous Oceanic Red Beds (Chuangde section), 6) Oceanic Anoxic Events 1a and 2 (Gucuo and Gongzha sections), and 7) the Paleocene–Eocene Thermal Maximum (Shenkezha section).

Important Dates and Places:

Workshop

August 16, 2025: Registration at Nanjing University Xianlin Campus, Nanjing, Jiangsu.
