  • publication, discussion and comparison of research results,
  • encouraging the interchange of research, particularly where international cooperation is desirable,
  • promoting integration with other disciplines.

Feature comparison



The journals SEDIMENTOLOGY and THE DEPOSITIONAL RECORD are the official scientific publications of the IAS. The association is also involved in other journals and publishes Special Publications from time to time. The newsletter (bimonthly) keeps the members informed.


International Sedimentological Congresses (ISC) are held every four years. Regional and Thematic Meetings (International Meetings of Sedimentology, Summer Schools, Lecture Tours) are held between ISC's. The IAS does not organise conferences by itself, but acts as a sponsor.

Grants & sponsorship

To promote the study of Sedimentology, the IAS offers PhD students in the field of Sedimentology 2 types of grants: postgraduate research grants (PGS) and travel grants. Sedimentology researchers in least developed countries can apply for an institutional grants (IIGS).

National Correspondents

Each country with more than five members or countries decided by the Bureau has a National Correspondent. They inform the IAS of sedimentological activities and assist in obtaining members within their particular country. Together National Correspondents in more than 50 different countries currently form a strong global sedimentological network.
