* Ultramafic rocks: These rocks form deep within the Earth's mantle, and peridot is a key component of them.
* Meteorites: Peridot can also be found in meteorites, which are remnants of asteroids or other celestial bodies.
Here's why:
* Formation: Peridot (a form of olivine) forms under high pressure and heat deep within the Earth's mantle.
* Eruption & Exposure: Volcanic eruptions can bring these ultramafic rocks containing peridot to the surface, where they can be found in specific geological locations.
Where to find peridot:
* Arizona, USA: The San Carlos Apache Reservation in Arizona is known for its peridot deposits.
* Myanmar (Burma): This country is a major source of high-quality peridot.
* Pakistan: The Hunza Valley in Pakistan has significant peridot mines.
* Other locations: Peridot can also be found in smaller quantities in other parts of the world, including Australia, Brazil, China, and Egypt.
Important note: While peridot can be found in some surface rocks, it's not typically found in large quantities or in easily accessible locations. The vast majority of peridot comes from the mantle, where it's brought to the surface through geological processes.
