The International Association of Sedimentologists (IAS) is a professional organization dedicated to the study of sedimentology, which focuses on the processes of sediment formation, transport, and deposition. Founded in 1961, the IAS aims to promote research and education in sedimentology and related fields, fostering collaboration among scientists worldwide. The association organizes conferences, publishes scientific journals, and provides resources for sedimentologists. It also supports the development of young researchers through various initiatives. By connecting professionals in the field, the IAS plays a crucial role in advancing knowledge about sedimentary processes and their implications for geology and environmental science.
