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).
A ngular Unconformity Disconformity Nonconformity An angular unconformity, as its name suggests, is an unconformity between layers that are not parallel but instead are at an angle. T he upper, hori-zontal, layers were de posited atop the erosion surfac e, so we can st ep back in time by removing t hem. Steno's principle of lateral continuity
