The term “deep-sea fan” has been coined by Normark (1970) to describe modern turbidite systems with a point source that typically display a fan-shaped outline. This morphological analysis was based on the Pleistocene Californian fans San Lucas and Astoria. Mutti and Ricci Lucchi (1972) used a similar model to describe the fan-shaped facies association of Cretaceous and Tertiary turbidite systems in the Apennines and Spanish Pyrenees.
The Depositional System
Models that are more recent try to make a synthesis between morphology, sedimentary processes, depositional environment, and sedimentary facies (Walker, 1978; Mutti, 1979; Barnes and Normark, 1985). They include control factors such as sedimentary source, tectonic context, and eustatic changes.
The term “turbidite system” was thus preferentially used to embrace all deepwater clastic depositional systems. The environmental model of Reading and Richards (1994)...
