Most coarse-grained clastic sediment that is deposited in turbidite basins is either derived from alluvial basins or shallow marine shelves. |
|
Greywacke is an old term still sometimes used for a particular type of wacke especially in grey-coloured turbidite sequences. |
|
Thick shale packages, approaching 30 m thick, occur interbedded with the turbidite sandstones. |
|
Both turbidite units are sand rich, and typically interpreted as the deposits of high-density turbidity currents. |
|
Two endmember scenarios are defined as possible models to explain the different mineral-chemical stratigraphical styles shown by turbidite sandstones. |
|
The group is subdivided into formations, which each represent a turbidite lobe, and are separated by anoxic background sedimentation. |
|
Discoveries to date are stratigraphic traps comprising Turonian and Campanian turbidite fans drilled in water depths of 500-2,500 metres. |
|
The rock sequence formed by a turbidity current is called a turbidite. |
|
Turbidite deposits and westward younging of limestones and evaporites record the development of the foreland fold and thrust belt during the Late Carboniferous Epoch. |
