The International Geoscience Programme (IGCP) 572 is targeting the Permian-Triassic mass extinction and subsequent recovery with emphasis on ecosystem’s restoration after the greatest death of Earth life. One of her major activities in 2010 is to investigate the P-Tr ecosystem’s collapse and rebuilding in low-latitude regions. South China records the spectacular P-Tr boundary and Lower-Middle Triassic sequences and thus enables to test the tempo and mechanism of the marine ecosystems’ collapse in the P-Tr mass extinction and subsequent recovery. Thus, IGCP 572 is sponsoring an Annual Meeting and Field Workshop at the International Geobiology Conference (ICG2010).

This symposium aims to investigate the mechanisms of ecosysem’s collapse and rebuilding in the P-Tr mass extinction and its aftermath through multidisciplinary studies. The topics will address: causes and pattern of P/Tr mass extinction, Early Triassic microbialites, recovery patterns of various fossil groups and ecosystems. We will also organize three field excursions, including: A1 (pre-conference): GSSPs of the Changhsingian and P-Tr boundary (Changxing, Zhejiang) and Lower Triassic sequences and biota (Chaohu, Anhui); B1 (post-conference): Geobiology of P-Tr microbialite and carbonate petroleum source rocks in Chongqing-Guangyuan areas, western China; B3 (post-conference): P-Tr boundary to Middle Triassic sequences and ecosystems in various facies in Guizhou. In particular, during the excursion B3, we will investigate the well-known Qingyan biota of Anisian age, ~300 fossil species recorded in a 90-m-thick unit, which marks biotic recovery from the P-Tr crisis. Ecosystem recovery through Early-Middle Triassic will be examined in various facies settings. The exceptionally preserved Early Triassic trace fossil Lagerstätten nearby the Guiyang City will also be investigated.

Small travel grants are also available for IGCP 572 members to apply and support their participation in the Wuhan conference and field excursions.
