A disconformity is also called a parallel unconformity. It is a discontinuity surface between two sets of rocks in the same location. It can form due to extensive uplift of land, which is then subject to denudation to form a lacuna and then to extensive sedimentation again upon subsequent subsidence. A disconformity is mainly characterised by the upper and lower rock sequences that are parallel to each other; and, in other words, no crustal movement has occurred. A disconformity is also called a false conformity.
