In the example below, the contact between the conglomerate and the granite beneath it appears likely to be a nonconformity.However, it is possible that the granite may have intruded as a magma within the crust, beneath conglomerate, after the conglomerate formed.

Relative age dating of sedimentary rocks

The angular unconformity is the contact between the younger layers of sediment and the older, tilted strata beneath.

A nonconformity is an unconformity with sedimentary or volcanic strata on top and, beneath it, either plutonic rock such as granite or metamorphic rock such as schist.

After being tilted or folded, the older layers of sediment were eroded.

Then younger layers of sediment were deposited on them.

Another essential concept in stratigraphy is the unconformity.
