Submarine sedimentation on a developing Holocene fan delta

Sedimentology, 1989
ABSTRACTThe submarine morphology, sediments, and three‐dimensional geometry of a developing fan delta are described using data from acoustic surveys, bottom sampling, and observations from a manned submersible. The fan system is being built in a British Columbian fjord (water depth 410 m) supplied with coarse‐grained sediments from a fjord‐side river ...

Longshore Drift, Submarine Canyons, and Submarine Fans in Development of Niger Delta

AAPG Bulletin, 1972
ABSTRACT The southwesterly prevailing wind of the Gulf of Guinea strikes symmetrically on the nose of the Niger delta, causing divergent longshore drifts which meet opposing drifts near Lagos and Fernando Poo. Submarine canyons channel about 1 million cu m of sand a year from each pair of opposing drifts to feed submarine fans on ...

Transitional submarine fan deposits from the late Precambrian Kongsfjord Formats submarine fan, NE Finnmark, N. Norway

Sedimentology, 1983
ABSTRACT Three transitional submarine fan environments are recognized in the late Precambrian, 3‐2 km thick Kongsfjord Formation in NE Finnmark, North Norway, namely: (1) middle to outer fan; (2) fan lateral margin, and (3) fan to upper basin‐slope deposits.

Ancient Submarine Canyons and Fan Valleys

1974
Abstract Many modern submarine canyons and deep-sea fans originated in pre-Pleistocene time. Similar submarine canyons, fans, and fan valleys are found in the geological record certainly as far back as the Precatnbrian. Criteria for recognizing ancient submarine channels include: (1) proved or inferred size comparable to modern ...

Quaternary Styles of California Submarine Fans: ABSTRACT

AAPG Bulletin, 1980
The morphology and sedimentation patterns of large, deep-ocean submarine fans along the California coast, like Monterey fan, differ from that of smaller borderland or slope-basin submarine fans like the Navy and La Jolla fans. Small borderland fans feature areas of channels, isolated depressions, and a convex upward profile which are characteristic of ...

Seismic Stratigraphic Expression of Submarine Fans

1985
Abstract This paper presents criteria for recognizing ancient submarine fans from seismic data, and illustrates examples of seismically defined fans as well as common “pitfalls” of fan interpretation. Submarine fans usually can be recognized seismically by morphology and by position in the overall paleogeographic setting.

Seismic Stratigraphic Criteria for Recognition of Submarine Fans

1984
This paper presents criteria for recognizing ancient submarine fans from seismic data and illustrates examples of seismically defined fans as well as common “pitfalls” of fan interpretation. Submarine fans usually can be recognized seismically by morphology and position in the overall paleogeographic setting.
