Graded bedding is the primary sedimentary structure which is most closely associated with turbidity currents.
Primary sedimentary structure
This structure was formed during the sedimentation process , thereby reflecting the mechanism of its deposition .
Examples of primary sedimentary structures are:
- layer structure,
- wave structure,
- cross layering,
- convoluted structure,
- layered layering gradded bedding etc.
The most important structure of the above is the layered structure, because this layered structure is the main characteristic of clastic sedimentary rocks which produce parallel planes as a result of the depositional process.
The factors that affect the appearance of the layering structure are:
- There is a difference in the color of minerals,
- There is a difference in grain size
- There are differences in mineral composition,
- There is a change in the type of rock,
- There is a change in the structure of the sediment,
- There is a change in the compactness of the rock.
