The 2014 Field Workshop of IGCP 591 held jointly with ISOS and ISCS will be hosted by the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences and the Yunnan Key Laboratory of Palaeontology, Yunnan University. Its formal theme will be ‘Global Events and their relationships in the Early to Middle Paleozoic’. The meeting is scheduled tentatively for August 18-28, 2014. The scientific sessions in Kunming will be followed by a field excursion from northeastern Yunnan (western South China paleoplate) to western Yunnan (Indochina and Sibumasu paleoplates).

The meeting in Kunming will include two days of indoor scientific sessions for delegates to present their most recent research, and a day trip to the world-renowned Chengjiang Biota site, about 60 km east of Kunming.
