Cross Bedding Types
Cross bedding is a common sedimentary structure characterized by inclined laminations within a sedimentary deposit. It forms when sediment is deposited on a surface that is not horizontal, such as a sandbar or a ripple mark. The inclined laminations are formed as the sediment is transported and deposited by a current or wind. The type of cross bedding that forms depends on the nature of the current or wind and the type of sediment being transported. Some of the most common types of cross bedding include: *Trough cross bedding:
This type of cross bedding is characterized by a series of troughs, or depressions, in the sediment. The troughs are typically filled with coarser sediment than the surrounding sediment. *Planar cross bedding:
This type of cross bedding is characterized by a series of planar, or flat, surfaces in the sediment. The planar surfaces are typically composed of finer sediment than the surrounding sediment. *Festoon cross bedding:
This type of cross bedding is characterized by a series of festoon-shaped, or curved, surfaces in the sediment. The festoon-shaped surfaces are typically composed of coarser sediment than the surrounding sediment. The type of cross bedding that forms in a particular setting can provide information about the nature of the current or wind that deposited the sediment. For example, trough cross bedding is typically formed by a fast-moving current, while planar cross bedding is typically formed by a slow-moving current. Festoon cross bedding is typically formed by a wind-blown current. Cross bedding is an important sedimentary structure that can be used to interpret the depositional environment of a sedimentary deposit. By understanding the different types of cross bedding and the conditions under which they form, geologists can gain a better understanding of the history of a particular sedimentary deposit. ### Conclusion Cross bedding is a common sedimentary structure that can provide valuable information about the depositional environment of a sedimentary deposit. By understanding the different types of cross bedding and the conditions under which they form, geologists can gain a better understanding of the history of a particular sedimentary deposit.Crossbedding
