Stratigraphy & Chronology (SACCOM)
Stratigraphy and Geochronology Commission SACCOM
SACCOM focuses on Quaternary stratigraphy and chronology, offering a platform to discuss and standardize global stratigraphical research and classifications through meetings, publications, and public outreach.
The Stratigraphy and Geochronology Commission is devoted to studying the Quaternary Period through Quaternary stratigraphy and chronology. It provides a forum for Quaternary scientists to discuss and establish stratigraphical investigations and classification worldwide. It seeks to achieve this through the organization of regular meetings, publications, and publicity. In addition, a network of focus groups with specific mandates has been established under the auspices of the Commission.
Mission
SACCOM exists to promote and co-ordinate international co-operation and integration by:
- the establishment and publication of a geological timescale for the Quaternary,
- the unification of regional and national chronostratigraphical nomenclature,
- the promotion of stratigraphical methods, and the dissemination of stratigraphical knowledge,
- the evaluation of new stratigraphical methods and their integration into a multidisciplinary stratigraphy, and
- the definition of principles of stratigraphical classification, terminology, and procedure and their publication.
SACCOM scientific activities are carried out through projects, websites, publications, and meetings, mainly through focus groups dedicated to the investigation of specific areas of the discipline, through collaboration with other INQUA Commissions, and outside organizations
