Clay is the most common mineral in Metamorphic rocks

Explanation:

Metamorphic rocks -

Metamorphic rocks are formed under intense heat or pressure.

High temperature and pressure is possible inside deep earth's crust, therefore, the sedimentary rocks and the igneous rocks can be changed into metamorphic rock.

Then, these rocks cools down and crystallizes into bands of crystal, and later get exposed to the earth's surface.

The metamorphic rock can be determined by the bands of crystal on the surface of rock.

Clay is a very important mineral in metamorphic rocks such as slates, phyllites, schists which show foliations.
