About the Association

Founded to promote the study of Sedimentology and to bring together sedimentologists from around the world

The International Association of Sedimentologists (IAS) was founded at the International Geological Congress in Algiers on 11 September 1952.  Sedimentology is the scientific discipline that is concerned with the physical and chemical properties of sedimentary rocks and the processes involved in their formation, including the origin, transportation and deposition of sediment in diverse environmental settings and the transformation of sediment into rock (lithification).
