Angular Unconformity in Cerberus Fossae,as seen by HiRISE. Location is 9 degrees north latitude and 162.9 degrees east longitude. Image was taken by the Mars Reconnaissance Orbiter's HiRISE. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona.

An unconformity is a widespread surface separating rocks above and below, ... The most easily recognized are angular unconformities, which show horizontal layers of sedimentary rock lying on tilted layers of sedimentary rock. The upper layers may not be perfectly horizontal, but they do not lie parallel to the lower layers.

The inner gorge of the Grand Canyon provides a great example of angular unconformity formation. Except, instead of four steps, the rocks tell of seven: (1) Over two billion years ago, layers of sediment accumulated and turned to rock.

Because of the Laws of Stratigraphy, if we see a cross section like this in a road cut or canyon wall where we can recognize an angular unconformity, then we know the geologic history or sequence of events that must have occurred in the area to produce the angular unconformity.
