Unconformities. 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).
ISO/IEC 9126 distinguishes between a defect and a nonconformity, a defect being The nonfulfilment of intended usage requirements, whereas a nonconformity is The nonfulfilment of specified requirements.
