Unconformities. Unconformities are gaps in the geologic record that may indicate episodes of crustal deformation, erosion, and sea level variations. They are a feature of stratified rocks, and are therefore usually found in sediments (but may also occur in stratified volcanics).
Click the image to see the animation. Use the movie controls to examine the stages. An unconformity is a gap in the sedimentary rock record. This animation shows the formation of an angular unconformityone where the layers above and below the unconformity are not parallel to each other, but form an angle. Examine how the final result allows you to infer the sequence of the rocks' formation.
