WebDisconformity; At a disconformity, beds of the rock sequence above and below the unconformity are parallel to one another, but there is a measurable age difference between the two sequences. The disconformity surface represents a period of nondeposition and/or erosion (Figure 1. a). Try This Cross Section Interpretation Exercise WebTherefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed. Unconformities are classified as three types. The most easily recognized are angular unconformities, which show horizontal layers of sedimentary rock lying on tilted layers of sedimentary rock.
