Unconformities
At this location you can see an paraunconformity. 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). They are surfaces between two rock bodies that constitute a substantial break (hiatus) in the geologic record (sometimes people say inaccurately that "time" is missing). Unconformities represent times when deposition stopped, an interval of erosion removed some of the previously deposited rock, and finally deposition was resumed. deposition is were in sedaments and rock are added to the land mass when the forces resposible for movement are no longer able to overcome to forces of gravity creating a resentance to the area making layers form
