What is the best definition of a turbidite?
Turbidite meaning Any sediment or rock deposited by a turbidity current. Turbidites usually consist of a sequence of sediments in which the bottom layers contain the coarsest grains and the upper layers the finest, such as a sequence of sand that is overlain by silt, which in turn is overlain by clay.
How do you identify turbidite?
Classic, low-density turbidites are characterized by graded bedding, current ripple marks, climbing ripple laminations, alternating sequences with pelagic sediments, distinct fauna changes between the turbidite and native pelagic sediments, sole markings, thick sediment sequences, regular bedding, and an absence of …
What type of sedimentary rock is turbidite?
turbidite, a type of sedimentary rock composed of layered particles that grade upward from coarser to finer sizes and are thought to have originated from ancient turbidity currents in the oceans.

What is the difference between turbidite and turbidity current?
Turbidity currents are underwater gravity flows triggered by the mobilization of sediments on a slope. The lithified product of a turbidity current is a turbidite, which is a graded layer that generally contains a coarse-grained base and a fine-grained top (conglomerate to coarse sandstone to mudrock).
How is turbidite formed?
Turbidites are sea-bottom deposits formed by massive slope failures. These slopes fail in response to excessive sedimentation load and sometimes earthquake shaking, sending the sediments sliding down to the ocean bottom to create a turbidite.

What is the best definition of a turbidite quizlet?
Turbidites: -the sediment that is deposited by a turbidity current is called a turbidite. -These are well-sorted and well-graded sediments (which means that as the current speed slows down progressively finer sediments are deposited. ) -Turbidites are found on continental slopes and rises. Only $35.99/year.
What is turbidite sandstone?
Turbidites are sea-bottom deposits formed by massive slope failures. The sandstone beds were formed in a deep basin by turbidites coming from a delta area.

What are turbidite deposits?
Turbidites are sea-bottom deposits formed by massive slope failures. Rivers flowing into the ocean deposit sediments on the continenal shelf and slope. The sandstone beds were formed in a deep basin by turbidites coming from a delta area.

How does a turbidite form?
What are turbidite beds?
Definition. A turbidite is a sedimentary bed deposited by a turbidity current or turbidity flow. It is composed of layered particles that grade upward from coarser to finer sizes and ideally display a (complete or incomplete) Bouma sequence (Bouma, 1962).
