报告简介：
The notion of time is fundamental for understanding the history of the Earth. Today, the International Geological Time Scale composed of well-defined time units is invariably linked to the term GSSP that is symbolized by a golden spike. Currently, a significant number of golden spikes are still missing for the division of the Carboniferous Period. In this presentation, Prof. Aretz will explore some of the challenges Carboniferous stratigraphers faced, and discuss the current Carboniferous chronostratigraphy and the completion of the remaining GSSPs. This talk will also emphasize that standards we apply today for defining a GSSP are much higher than in past decades, which require multi-proxy approaches and a more complex and comprehensive understanding of a boundary interval. The Carboniferous stratigraphic community is currently embracing this challenge and we will explore how it may influence and impact the subdivision of the Carboniferous and the establishment of the next GSSPs.
