Examples of metamorphic rocks. Metamorphic rocks are formed form pre existing rocks through the process of metamorphism. Other examples include quartzite hornfels and novaculite. Remember these rocks are formed under extreme heat and pressure.

Slate is another common metamorphic rock that forms from shale. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
