Answer:
metamorphic rock
Explanation:
Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.
Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.
- At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks.
- These changed rocks have different mineral facies that are different from those of the prolith.
Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.
