Submarine fans can be classified into four types based on their tectonic settings: (1) immature passive-margin fans (North Sea type); (2) mature passive-margin fans (Atlantic type); (3) active-margin fans
The term “ submarine fans ” refers loosely to deposits of variable shapes and sizes in deep-marine environments (Fig. 23). The principal elements of submarine fans are canyons, channels, and lobes. The world's largest submarine fan, known as the Bengal Fan, has a length of 3000 km, a width of 1430 km, and a sediment thickness of 16.5 km.
5 Μαΐ 2018 · Ancient submarine fan deposits illustrated here include: the Lower Miocene Waitemata Basin near Auckland, New Zealand; the Paleocene of Point San Pedro, Upper Cretaceous Pigeon Point, and Dana Point successions, all in California; and Proterozoic examples from Belcher Islands (about 1800-1900 Ma).
1 Ιουλ 2017 · In this chapter we describe the wide range of morphological features recognised on the surfaces of submarine fans, and the physical processes that shape the seabed in areas where submarine...
19 Ιουλ 2017 · Submarine fans are complex morphological features that develop on the continental slope, rise and abyssal plain, normally at the mouths of submarine canyons. They are constructed principally from the deposits of sediment gravity flows (mainly turbidity currents and...
Submarine fans form on both active and passive margins, in relatively shallow (<500 m) to very deep water (>4000 m), at both high and low latitudes, in oceans and in lakes. The diverse range of submarine fan settings is matched by their architectural variability and wide range of dimensions.
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. … Expand
