The Subcommission is the primary body for facilitation of international communication and scientific cooperation in Cryogenian stratigraphy directed at better understanding Earth system evolution during the Cryogenian Period (c.720 – c.635 Ma). Its priority is the unambiguous definition, by means of global stratotype section and points (GSSP), of a hierarchy of chronostratigraphic units that provide the framework for correlation of Cryogenian strata.
The Subcommission is organized by an Executive consisting of Chair, Vice-Chair and Secretary, who are all Voting Members of the Subcommission. These officers were appointed by ICS in 2020. August, 2024, we are welcoming the 20 new Voting Members, making a total of 23 voting members. We give our warm thanks to the previous 18 voting members .

The main goals of this Subcommission are:
In addition, the Subcommission is committed to expanding communication to a wider public through grassroots initiatives to conserve important Neoproterozoic geological sites, to support International Geoscience Programme projects, and to encourage the wider dissemination of research findings on the internet, in popular science publications, and through public lectures.
