Turbidity currents are subaqueous sediment gravity flows that are generated by landslides, slumps or density-based avalanches (Mutti et al.
Deposits of turbidity currents, i.e., turbidites, can be found in different geological settings such as lakes, reservoirs, delta fronts and continental shelves (Walker 1976).
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
. The source of most of the Motatau detritus plutonic quartz within this sandstone is considered as plutonic protolith.

That suggests that a geologically recent canyon-scouring turbidity current
had passed through, depleting the chasm of material that previously had accumulated, she notes.
According to Shor, "smaller bedforms develop from fast tidal currents in shallow water, but normally the flows in deep water aren't strong or persistent enough to form [such large features in gravel]." 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.
The most fascinating attributes of turbidity currents
, their high speeds and their ability to transport coarse sediment into deep water, are also those that make them difficult to study with ocean-drilling techniques.
