A prerequisite for geological research and the production of geological maps is the subdivision of rock strata into mappable, named units, a sub-discipline of geology known as 'stratigraphy'. In order to promote the orderly development of stratigraphic classification and nomenclature in South Africa, the South African Committee for Stratigraphy (SACS) was formed in 1971 with four main objectives, viz.
Eighteen task groups, each comprising specialists on a specific part of the geological column, assist SACS in carrying out its mandate. All SACS activities are funded by the Council for Geoscience (CGS), with the SACS Secretary being a full-time employeee of the CGS.
SACS is an organisational member of the International Sub-commission on Stratigraphic Classification (ISSC) of the International Commission on Stratigraphy (ICS), the largest scientific body of the International Union of Geological Sciences (IUGS).
