WebThere are three kinds of unconformities: disconformities, nonconformities, and angular unconformities. Disconformities. Disconformities (Figure 1) are usually erosional … Web3 Aug 2024 · Unconformities are a type of geologic contact—a boundary between rocks—caused by a period of erosion or a pause in sediment accumulation, followed by … A nonconformity is the contact that separates a younger sedimentary rockunit from an igneous intrusive rock or metamorphic rock unit. A nonconformity suggests that a period of long‐term uplift, weathering, and erosion occurred to expose the older, deeper rock at the surface before it was finally buried by the … See more Disconformitiesare usually erosional contacts that are parallel to the bedding planes of the upper and lower rock units. Since disconformities are hard to recognize in a layered sedimentary rock sequence, they are … See more An angular unconformityis the contact that separates a younger, gently dipping rock unit from older underlying rocks that are tilted or deformed layered rock. The contact is more obvious than a disconformity … See more Nonconformities are due to relative changes in sea level over time.
