Garnet: The Gemstone of Metamorphic Rocks!

Yes, garnet is a common mineral found in metamorphic rocks.

Garnet is a type of mineral that is commonly found in metamorphic rocks. It is known for its deep red color and is often used in jewelry making. When rocks undergo metamorphism, minerals within the rocks can recrystallize and grow larger. Garnet is one of the minerals that can form during this process, known as a porphyroblast.

Porphyroblasts are minerals that form during metamorphism and are larger than the surrounding matrix. Garnet is a common type of porphyroblast. During metamorphism, rocks with a shale protolith will have minerals such as quartz, feldspar, and muscovite mica. These rocks can also contain porphyroblasts like garnet.

Overall, garnet is a beautiful gemstone that not only makes stunning jewelry but also plays a significant role in the formation of metamorphic rocks.
