Geological unconformity
Geological unconformity
An example of unconformity. An unconformity is a buried erosional surface separating strata of different ages; it indicates that sediment deposition was not continuous. In an angular unconformity, such as the one shown here, younger strata of sedimentary rock rest upon the eroded surface of tilted or folded older rocks.
