Metamorphic Rocks Mine Engineer.Com provides mining

Metamorphic rocks are classified by texture and composition. Two major types of texture in metamorphic rocks are foliated and non foliated. Non-foliated texture means the minerals contained in the parent rock were not conducive to layering, or temperature was dominant over pressure in the metamorphic process, and it has a granular texture.

A Very Simple Metamorphic Classification

Metamorphism is the alteration of a preexisting rock (the parent rock) due to heat and pressure caused by burial in the earth.The parent rock must adapt to the new conditions and it does so by changing mineral composition and texture. These rocks with new texture and composition are metamorphic rocks.
