Sills and d(i)kes

Explanation:

Sills are distinct geological features that are usually found in an outcrop. These are considered to be a concordant igneous intrusive body that is oriented parallel to the country rocks.

On the other hand, d(i)kes is the discordant igneous intrusive body that cuts across the country rocks, at some angle or in a perpendicular manner.

Both these features are important and they are sometimes comprised of valuable minerals in them, and they are younger than the adjacent and surrounding country rocks.
