Unconformities
An unconformity is contact between two rock units.Unconformities are typically buried erosional surfaces that can represent a break in the geologic record of hundreds of millions of years or more. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity. An expected age of layer or layers of rock is/are missing due to the erosion; and, some period in geologic time is not represented.
