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. There are currently 18 other Voting Members, making a total of 21 voting members.
