Question … WebTurbidites are the deposits of turbidity currents and commonly show graded bedding with a sequence of sedimentary structures indicative of waning flow during the passage of the turbidity current (Ye et al., 2024), and progressively declining bed shear stress during deposition of the bed (Kneller, 2003 ).
WebThe resulting layer of sediment that the turbidity current deposits are called a turbidite. A number of events can trigger turbidity currents including: tsunamis, storm induced waves, slope failures and earthquakes. Typically … WebOct 1, 2024 · In general, turbidite lobe deposits appear as tabular, parallel/sub-parallel sandstone and mudstone interbeds, and change from thick, massive sandstone in the proximal end to thinner sandstone and mudstone interbeds from axis to fringe, with the sand-shale ratio and degree of sandstone amalgamation decreasing.

The distinction is that, in a normal river or stream bed, particles of rock are carried along by frictional drag of water on the particle (known as tractional flow). The water must be travelling at a certain velocity … See more A turbidite is the geologic deposit of a turbidity current, which is a type of amalgamation of fluidal and sediment gravity flow responsible for distributing vast amounts of clastic sediment into the deep ocean See more Submarine fan models are often based on source-to-sink [S2S] concepts linking sediment source areas, and sediment routing systems to the eventual depositional environments of turbidite deposits.
