A geologic unconformity occurs when an earlier rock formation has been distorted or partially eroded before a newer rock layer, often sedimentary, is set down.
As a result, the rock strata are misaligned.
What causes nonconformities?
An unconformity is a broad surface that separates rocks above and below, indicating a void in the rock record. Unconformities occur when rocks are worn away by erosion or when rock deposits never form.
As a result, there is a temporal gap between the formation of the rocks below the unconformity and those above it.
