ICS Subcommission on Quaternary Stratigraphy


Pianico laminated lacustrine sequence, Northern Italy

The Subcommission on Quaternary Stratigraphy (SQS) is a constituent body of the International Commission on Stratigraphy (ICS), the largest scientific organisation within the International Union of Geological Sciences (IUGS).

It is also the only body concerned with stratigraphy on a global scale for the whole geological column. Its most important major objective is the establishment of a standard, globally-applicable stratigraphical scale, which it seeks to achieve through the co-ordinated contributions of a network of Subcommissions and Working Groups with a specific, limited mandate.

The SQS exists to promote and co-ordinate international co-operation and integration by applying the statutary scientific goals of the ICS to the Quaternary - the most recent geological system, the last 2.6 Ma:

The scientific activities are carried out through projects, websites, publications and meetings, particularly through close co-operation with our sister organisation the International Union of Quaternary Research (INQUA), INQUA - Commission on Stratigraphy and Chronology (SACCOM), as well as through collaboration with other organisations.
