The type of metamorphic rock that results from the metamorphism of granite depends on the specific conditions of metamorphism, such as temperature, pressure, and the presence of fluids. Here are some possibilities:

* Gneiss: This is the most common metamorphic rock derived from granite. It's characterized by a banded appearance due to the alignment of minerals like quartz, feldspar, and mica.

* Migmatite: When granite undergoes high-grade metamorphism, it can partially melt, resulting in a mixture of igneous and metamorphic rocks. This mixed rock is called migmatite.

* Schist: If the metamorphism is less intense, granite can transform into schist, which is characterized by a foliated texture with larger crystals.

* Hornfels: If the metamorphism is contact metamorphism (caused by the heat of an intrusion), granite can transform into hornfels, a non-foliated, fine-grained rock.

The exact type of metamorphic rock will depend on the specific conditions and the original composition of the granite.
