Here's why:
* Heat and Pressure: These are the key ingredients for creating garnet. They come from deep within the Earth, often associated with metamorphic processes.
* Recrystallization: The heat and pressure cause the existing minerals to break down and rearrange their atomic structure. This process creates new, more stable minerals, including garnet.
Garnet is a metamorphic rock, meaning it is formed through these changes in existing rocks. The specific minerals present in the original rock, along with the intensity of heat and pressure, determine the type of garnet that is formed.
