Marine Geology, 1968
Abstract The submarine fan built into San Diego Trough off La Jolla, California, is creased by a steep-sided valley that “hooks” left, as do most fan-valleys off the western United States. Close-spaced, well-controlled sounding lines have allowed detailed contouring of the feature.

Submarine fan complex offshore Mauritania
54th EAEG Meeting, 1992A giant fan complex lies offshore Mauritania, in moderate waters. It extends over 160 km in the east-west direction, from the shelf-break to the west, and 80 km in the north-south direction. It has accumulated over more than 3000 metres of deposits from Aptian to Paleocene in age.

Submarine Fan Models: Problems and Solutions
1985Submarine fan models have created considerable confusion in the literature because of misuses of terminology and concepts. We propose that ancient submarine fans should be considered only as systems in which lobes are attached to feeder channels. The popular detached lobe model is based solely on the Eocene Hecho Group in Spain.

Eustatic Control of Submarine Fan Development
1985Global changes in sea-level control both siliciclastic and calciclastic turbidity-current deposition in the deep sea. On modern active and passive margins, growth of submarine fans occurred mainly during the Pleistocene glacials (low sea-level). During interglacials (high sea-level), most fans were dormant.

Calciclastic submarine fans: An integrated overview
Earth-Science Reviews, 2008Abstract Calciclastic submarine fans are rare in the stratigraphic record and no bona fide present-day analogue has been described to date. Possibly because of that, and although calciclastic submarine fans have long intrigued deep-water carbonate sedimentologists, they have largely been overlooked by the academic and industrial communities.

The Crati Submarine Fan, Ionian Sea
Geo-Marine Letters, 1983The Crati Fan is located in the tectonically active submerged extension of the Apennines chain and foretrough. The small fan system is growing in a relatively shallow (200 to 450 m), elongate nearshore basin receiving abundant input from the Crati River.

Depositional Model for Submarine Fans
AAPG Bulletin, 1981End_Page 958------------------------------Sand deposition on the Dume submarine fan off southern California is localized in the prominent leveed channels on the upper fan and on suprafans. The sand-laden turbidity currents, confined to channels by high levees in the upper reaches of the fan, overtop the low levees in the suprafan area and deposit their

Stratigraphy of an Archean submarine fan
Precambrian Research, 1980Abstract This paper describes the occurrence of iron-formation in a submarine fan environment of the Archean of Ontario. A section, over 500 m thick, of greywacke turbidite, shale, siltstone, sandstone, conglomerate, and three iron-formations is well preserved.

Congo Submarine Canyon and Fan Valley
AAPG Bulletin, 1973Seventeen transverse profiles of the inner 460 km of the Congo Canyon and the Congo Fan Valley were made during a 4-day study in June 1972. These profiles show that the canyon is V-shaped with side slopes 400-1,400 m high between the coast and a point 240 km seaward, where the axial depth is about 2,700 m.

The Bengal Submarine Fan, Northeastern Indian ocean
Geo-Marine Letters, 1983Bengal Submarine Fan, with or without its eastern lobe, the Nicobar Fan, is the largest submarine fan known. Most of its sediment has been supplied by the Ganges and Brahmaputra Rivers, probably since the Early Eocene. The “Swatch-of-No-Ground” submarine canyon connects to only one active fan valley system at a time, without apprent bifurcation over ...
