Rock
metamorphic rock
It was metamorphosed at medium to high temperatures and has a higher degree of metamorphism than schist. The migmatite structure is developed. It is composed of a mineral composition similar to granite. Due to the deformation action, the shape of the leaves appears curved. Quartz is observed in the form of very thin veins.
