Abstract
Clinoforms constitute the basic building elements of continental margin growth.
Submarine clinoforms are composed of three geometric elements: topset, foreset and bottomset.
This study focuses on the determination of the distal termination of submarine deltaic clinoforms by
using morphometric criteria and subsequent validation with stratigraphic, sedimentological and
geochemical data. The mechanism and factors that potentially affect bottomset generation are also
discussed. These criteria have been applied to the Guadalhorce River prodelta, an environment
where advection and along-shore sediment transport prevail. We conclude that the seaward
advance of the prodelta is prevented by the current velocity increase at the foot of the morphosedimentary feature.
