Sedimentary, Tectonic, and Sea-Level Controlsber systems, two submarine fan types (elongate and radial), and a third nonfan, slope-apron system result primarily from variations in sediment type and supply. Tectonic setting and local and global sea-level changes further modify the nature of fan growth, the distribution of facies, and the resulting vertical stratigraphic sequences.

Eustatic Control of Submarine Fan Developmentdormant. In the rock record, the occurrence of most turbidites and winnowed turbidites closely correlates with lowstands of sea-level. Sea- level fluctuations appear to have been the primary control on fan growth throughout the Phanerozoic. In most cases, tectonism appears to be of secondary importance.

Submarine Fan Models: Problems and Solutionse Eocene Hecho Group in Spain. This technically controlled fan system should not be used as a general sedimentologic model for fans. Classification of fans into “highly efficient” and “poorly efficient” systems is not practical because individual fans often possess properties of both systems. Fans are most active during periods of low sea-level.

Amazon Fan, Atlantic Oceanplexes grow through channel migration, branching, and avulsion. Probably only one or two channels are active at any given time. Sediments reach the fan only during glacio-eustatic low stands of sea level. Coarse sediments largely by-pass the upper and middle fan via the channels and are deposited on the lower fan.

Bengal Fan, Indian Ocean system at a time, without apparent bifurcation over its 2500- km length. The upper fan is comprised of a complex of huge channel- levee wedges of abandoned and buried older systems. A reduction of channel size and morphology occurs at the top of the middle fan, where meandering and sheet flow become more important.
