It is proposed to build a section on the history of the development of the geological understanding of depositional system s has evolved and how depositional system s can now be related to their geomorphic position, their relationship to systems tracts, compositional lithology, geometries and the processes that. Depositional elements can vary from place to place and in the same place through time with changes of environmental parameters such as sandtomud ratio. The papers cover a wide spectrum of depositional environments ranging from alluvial fans to deepwater fans, in almost every climate type from arid through humid to glacial, and in a variety of tectonic settings.
