Question 64

Unconformities where layers below are parallel to layers above are called disconformities. Disconformities occur between parallel layers of sedimentary rock, representing a period of erosion or non - deposition.

The unconformity between older metamorphic or igneous rock and younger sedimentary rock is a non - conformity. Non - conformities form when sedimentary rocks are deposited on top of eroded igneous or metamorphic rocks.

Disconformities
