How does a metamorphic rock change into another type of metamorphic rock.. Unlike a foliated rock, there will be no layers and they will not flake apart into thin layers when broken. The phrases describe non-foliated rocks are: - Have randomly arranged grains - Include quartzite and marble - Form from crystallized magma. Explanation: egdy. Examples of nonfoliated rocks are quartzite, marble and anthracite coal. The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture, appearance and the type of pressure applied during recrystallization.
