Provenance of Motatau Complex indicates a distant or low relief source, but the presence of the glauconitic sandstone suggests intermittent influxes of coarse silisiclastic material, possibly by turbidity current
1986) respectively and indicate deposition by mixed low-concentration turbidity currents and hemipelagic sedimentation
1986), respectively, and indicate deposition by mixed hemipelagic and very low concentration turbidity currents.
It led to the first formal recognition of naturally occurring turbidity currents (Heezen et al.
2009, How of turbidity currents as evidenced by failure of submarine telecommunication cables, in Chiocci, F.
Although the k-[epsilon] Launder and Sharma model is applied here to a conservative salt solution density current, it seems that the analysis can be valid in general for turbidity currents laden with fine particles.
These factors again provide the conditions for minimizing the sediment deposition; thus, it seems that sedimentation rates can be greatly reduced by confining the turbidity currents.
In addition to revealing information on oceanic events and tectonic history of the adjacent land areas, the turbidite layers also provide information about some of the flow characteristics of the turbidity currents themselves.
However, many of the fundamental questions concerning the processes of turbidite deposition cannot be addressed on basin floors, reached only by occasional turbidity currents.
That suggests that a geologically recent canyon-scouring turbidity current had passed through, depleting the chasm of material that previously had accumulated, she notes.
Scientific instruments deployed off southern California have recorded the frequency and the violence of turbidity currents and provide hints as to what triggers them.
But as more surveys are conducted with sonar systems along coastlines where strong turbidity currents
might have flowed, it's likely that more gravel dunes will turn up.
