Bedding Layers Geology

Exposed by the downcutting of the Green River.

Bedding layers geology. Bedding complexes of rock of different age occur parallel to one another and the complex of upper layers repeats the forms of bedding of the lower layers. Bedding for example is the separation of sediments into layers that either differ from one another in textures composition colour or weathering characteristics or are separated by partings narrow gaps between adjacent beds Figure 619. Cross-beds are the groups of inclined layers and the sloping layers are known as cross strata.

Stratification or bedding is expressed by rock layers units of a general tabular or lenticular form that differ in rock type or other characteristics from the material with which they are interstratified sometimes stated as interbedded or interlayered. Cross-bedding is widespread in three common sedimentary. These surfaces display trace fossils indirect evidence of life such as tracks trails and burrows ripple marks mud cracks and cavities called vugs that are lined.

Examples of these are ripples dunes sand waves hummocks bars and deltas. Geological Survey of Western Australia Record 20059 71 pp. Normally the bedding of rocks is horizontal or very nearly so.

These are the beds of rock or strata. These sedimentary rocks were quarried with surfaces that correspond to the original bedding in the sediments that formed them. Beds are the layers of sedimentary rocks that are distinctly different from overlying and underlying subsequent beds of different sedimentary rocks.
