- A disconformity is an unconformity between parallel layers of sedimentary rocks.
- A non-conformity is an unconformity between two different rock types.
- A para-conformity is an unconformity between two parallels layers marked by differences in fossil age.
- An angular unconformity is an unconformity between two layers that are at an angle to one another.
The main cause of unconformity is usually non-deposition and erosion.
