👉 Pyrometamorphism is a geological process where igneous rocks, such as granite or quartz, melt and transform into metamorphic rock, which can then re-form into new igneous rocks. This occurs when the heat from the molten rock causes it to cool and solidify again. In other words, pyrometamorphism refers to the transformation of igneous rocks into metamorphic rocks due to the release of heat from the magma or lava.
