Chibanian GSSP Golden Spike - Installation Ceremony in Ichihara, Japan

21 May 2022 | 14:00 JST / 07:00 CEST


21 May 22 is a proud day for the international scientific community and especially for the International Union of Geological Sciences, the IUGS. The placement of the Golden Spike in the Chiba Section today marks the culmination of extensive studies of sites in Japan, Italy, and other countries by multi-disciplinary teams of geoscientists.


The voting members of the Subcommission of Quaternary Stratigraphy evaluated these investigations and approved the proposal for the section at Chiba to define the base of the Chibanian Stage that represents the Chibanian Age of the Pleistocene Epoch and Quaternary Period of the Geologic Time Scale.
