What Is Cross Bedding

What is Cross Bedding

Cross bedding is an essential aspect of sedimentary geology, as it is indicative of the depositional environment and processes that have acted on a particular sediment.

Cross bedding is a type of sedimentary structure that forms when sediment is deposited in layers that are inclined to the horizontal. This can occur in a variety of environments, including rivers, deltas, and beaches. The angle of the cross bedding can provide information about the direction of the current or wind that was responsible for depositing the sediment.

Cross bedding can also be used to determine the relative age of different layers of sediment. Layers that are cross-bedded are typically younger than layers that are not cross-bedded. This is because cross-bedding is only formed when sediment is being actively deposited. Once the sediment has stopped being deposited, the cross-bedding will be preserved.

In addition to its use in sedimentary geology, cross bedding can also be used to identify and track aquifers. Aquifers are layers of rock or sediment that contain groundwater. Cross bedding can provide information about the direction of groundwater flow and the permeability of the aquifer.

Overall, cross bedding is an important aspect of sedimentary geology that can provide a wealth of information about the depositional environment and processes that have acted on a particular sediment. It can also be used to determine the relative age of different layers of sediment and to identify and track aquifers.
