Twelve NIGPAS delegates led by Deputy Director Prof. WANG Xiangdong participated in the GSA 129th Annual Meeting in Seattle, USA from October 20th to 25th, 2017. The delegates gave oral or poster presentations, and took part in the workshops on foraminifers and IGCP653 during the meeting. Accompanied by Dr. Paul Brenckle, the world-known experts on the Carboniferous foraminifers, some of the delegates attended a post-conference field excursion in Mississipi Valley. Having a better understanding of the classical Mississipian strata in North America, the NIGPAS scientists checked more possibilities in the global stratigraphic correlation and the GSSP studies.
