    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 are 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.
