E)has both igneous and metamorphic characteristics

Question

Quizplus · Accepted Answer

Migmatite is a rock that shows both igneous and metamorphic characteristics. It forms when partial melting of a rock occurs during high-grade metamorphism. This process results in the formation of light-colored melted material or veins (igneous) within a darker-colored, solidified metamorphic rock. Migmatite is nonfoliated and can occur due to regional metamorphism. It does not always show rotational metamorphism.
