International Symposium on Deep-time Environmental & Climatic Extremes and Biotic Responses
22-24 May, 2018, Wuhan, China
IGCP630 and China University of Geosciences (Wuhan) invite you to participate in the International Symposium on Deep-time Environmental & Climatic Extremes and Biotic Responses in Wuhan, China, a beautiful city in central China. The Symposium will consist of a three-day meeting and be complemented by two field excursions before and one after the symposium, respectively to examine excellent marine and non-marine Permian–Triassic boundary sections, marine Lower-Middle Triassic successions as well as other major well-recorded extreme climate, environmental & biotic events (i.e., Snowball Earth event, O/S mass extinction, G/L mass extinction as well as life evolution processes during the critical periods of Earth history) in China.
The symposium will consist of presentations and posters that summarize main results that IGCP630 members and other researchers have obtained and focus on the causes and consequences of Permian–Triassic events and ecosystem recovery, as well as extreme climatic, environmental & biotic events during other critical periods in the geological past. Field excursions include: a three-day field excursion before the symposium to the well-studied Chaohu section, Anhui Province, examining the PTB and Lower Triassic successions and events (including well-known marine reptile fossil lagerstätten), and a four-day excursion before the symposium to Xian City and adjacent areas to investigate a non-marine Triassic succession recording ecosystem collapse and rebuilding on land, and a five-day excursion after the symposium to the classic long section recording the Ediacaran-Jurassic period of earth history in the beautiful Three Georges area, western Hubei Province.
The Symposium venue: China University of Geosciences (Wuhan) campus, China.
The Great Wuhan City is one of the most popular tourist destinations in China. Geographically, Wuhan is the heart of China, famous for spectacular riversides of the Yangtze River and many beautiful lakes within the city. It is also one of the most important industry, education and culture capitals in China. The city accommodates the largest population of undergraduate and graduate students (up to one million) in China, generating the hope for the future of this country.
The State Key Laboratory of Biogeology & Environmental Geology, and State Key Laboratory of Geological Process & Resource Geology, China University of Geosciences, the major sponsors of this symposium, are two of 40 state-level geoscience research centres in China. In these two centres more than 30 staff are working actively on the P/Tr mass extinction & Triassic recovery, and relevant topics. They are also training about 80 postgraduate students working on deep-time extreme events and relevant topics every year. China also records the most complete marine late Neoproterozoic to Triassic successions and terrestrial Triassic to Cenozoic strata as well as many important sites for studies on the P-Tr and other mass extinctions and climatic/environmental extremes in the world. Thus, the Symposium offers you unique opportunity to develop your collaborations with Chinese partners and take advantage of excellent geological record to probe into the deep of the P-Tr crisis as well as extreme climate/environment events in other critical periods.

The city of Xi'an (Capital of Shaanxi province) was the first Chinese city to open up its doors to the Ancient world during the Tang dynasty. As one of the most important cities in Chinese history, Xi'an was the capital for eleven dynasties. This city was a world leader in culture and trade and played a vital role in bridging the gap between east and west during the Tang Dynasty. Xi'an is also renowned for being the eastern terminus of the Silk Road and for the location of the Terracotta Army of Qin Dynasty. The city has more than 3,000 years of history. It was called Chang'an in ancient times. Aside from being a major tourist destination and historical city, today Xi'an has become an important cultural, industrial and educational center of the central-northwest region, with facilities for research and development and China's space exploration program. Xi'an is situated in the center of the Guanzhong Plains, surrounded by Mountains in the south and the Wei River in the north. More information is available in the following link:
The Qishuihe section is situated near the Tongchuan City, 100 km from Xi’an City (35.209°N, 109.056°E). An almost continuous outcrop records the Late Permian to Middle Triassic strata in the Qishuihe section. The P-Tr redbed succession is composed of the Sunjiagou, Liujiagou and Heshanggou formations. The Sunjiagou Formation consists of fine-grained sandstones, reddish siltstones and mudstones, containing Paleozoic-type plants and pareiasaurs. In addition, the Sunjiagou Formation contains marine bivalves and brachiopods in the Baoji and Tongchuan areas, which might indicate the occurrence of a transgression. Current researches suggest that the upper part of Sunjiagou Formation corresponds to the P-Tr transitional interval. The overlying Liujiagou Formation comprises reddish and brown-reddish fine-grained sandstones interbeded with siltstones and conglomerates. The Heshanggou Formation is composed mainly of purple siltstones and mudstones with diverse trace fossils.
3 Post-Symposium field excursion to Three Gorge area (5 days; May 25–29, 2018): Sedimentary succession from Ediacaran to Triassic with emphasis on the Permian/Triassic boundary up to Spathian successions in Three Gorge area, western Hubei, aiming to examine the Ediacaran Snowball Earth event, Precambrian-Cambrian event, O/S mass extinction, G/L mass extinction, P/Tr mass extinction, and Triassic recovery.
