Definitions:

Cleaved Rocks

Rocks that have been split or sliced along very smooth, flat surfaces, often due to intense pressure.

Unconformity

A boundary between underlying and overlying rock strata representing a significant break or gap in the geologic record; an unconformity represents an interval of nondeposition or erosion, commonly accompanied by uplift.

Intrusive Contact

The boundary between intrusive igneous rocks and the surrounding country rock into which they have intruded.

Axial Surface

A surface that connects the hinge lines in a fold.
