  • Metamorphic rocks are recycled rocks that have been subjected to varying degrees of pressure and temperature. As a result of all this extreme heating and pressure, old minerals become unstable and new ones begin to form. In many cases, the resulting rocks display a preferred orientation of minerals, as new minerals form perpendicular to the maximum pressure exerted .
