Turbidite - Wikipedia
Turbidites are sediments which are transported and deposited by density flow, not by tractional or frictional flow. 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 ).

In addition, abyssal plains are formed by the accumulation of turbidites beyond the limits of deep-sea fans and abyssal cones in locations where there is a very large sediment supply. Gerard V. Middleton
How is a turbidite actually deposited? | Science Advances
2022年1月19日 · The worldwide interest in turbidity currents and their deposits, the turbidites, is primarily for a geological understanding of deep-water turbiditic systems and their depositional facies tracts, palaeogeographic reconstruction of ancient deep-marine basins, hydrocarbon reservoir characterization, mass-flow geohazard assessment in modern deep ...
Turbidite - an overview | ScienceDirect Topics
Turbidites 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., 2017), and progressively declining …
Turbidites - Geosciences LibreTexts
Turbidites are subaqueous flows that begin with a slope failure. As sediment builds up and the slope gets steeper and steeper, and earthquake or simply oversteepening of the slope can cause a submarine debris flow, ie a turbidity current.
1.6: 6. Turbidites and Stratigraphy - Geosciences LibreTexts
Turbidites are subaqueous flows that start out with a very high sediment load and decrease in time to more normal flows. They have characteristic sedimentary structures associated with them that reflect these changes.

2016年1月1日 · Turbidites are the most common and archetypal deposits forming deep-marine clastic systems at the base of a slope along continental margins – together with related gravity-flow deposits and hemipelagic and pelagic sediments.
Turbidites - SpringerLink
Turbidites are the deposits of turbidity currents, which are gravity-driven turbid suspensions of fluid (usually water) and sediment. They form a class of subaqueous sediment gravity flow (see Gravity-Driven Mass Flows) in which the suspended sediment is supported during transport largely or wholly by fluid turbulence. Turbidites range in grain ...
Distinguishing between Deep-Water Sediment Facies: Turbidites …
2020年2月13日 · Turbidites are defined as all those sediments deposited by turbidity currents. They are geologically instantaneous event deposits, although the deposition of a single turbidite bed may take minutes (gravels and coarse sands) to a few days (fine silts and muds).
