Using cross-bedding to find the directions of ancient currents

Following on from the post of 5th September about cross-bedding and 'way-up' structures, we now have an ELI about using cross-bedding to find the directions of ancient currents. 'Sedimentary structures - cross-bedding and ancient currents'

Cross-bedding is a common feature of sedimentary rocks. The formation of cross- bedding can be seen in modern depositional environments and then related to similar structures in sedimentary rocks – an example of using the present to help us to understand the past. Cross-bedding can be used as part of prospecting in the minerals or hydrocarbon industries.
Many more activities about sedimentary structures can be found on our website.
