Stratigraphy of an Archean submarine fan

Precambrian Research, 1980
Abstract 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.

La Jolla submarine Fan-Valley

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.

A Devonian submarine fan in western Argentina

Journal of Sedimentary Research, 1976
Abstract The Punta Negra Formation (Middle to Upper Devonian of the Precordillera of western Argentina) consists of a monotonous sequence of graywackes and shales. It increases in thickness from east to west reaching a maximum of about 1,700 m.

Depositional Model for Submarine Fans

AAPG Bulletin, 1981
End_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

Congo Submarine Canyon and Fan Valley

AAPG Bulletin, 1973
Abstract Seventeen 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.

Submarine Fan Models: Problems and Solutions

1985
Submarine 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.
