WebAn unconformity is a large gap in the stratigraphic record that formed when deposition ceased for a considerable time. Most unconformities have resulted from relative uplift, which causes the erosion of some of the previously formed record. Wherever sedimentary sequences have been studied, they are interrupted by such gaps.
