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 .
