When metamorphic rock changes to magma the magma rises and cools to become?

A metamorphic rock is formed by the elements, minor heat, and compression. When the metamorphic rock is melted by magma, this would indicate that the metamorphic rock is under the surface of the earth. If it rises and cools again you will have an extrusive igneous rock. In a lot of cases, this is metamorphic rock on the surface under the influence of lava. This would change the composition and it would not longer be metamorphic, but rather igneous.
