What is periotite?

Answer 1

Peridotite is a dense, coarse-grained igneous rock primarily composed of the minerals olivine and pyroxene. It is typically found in the Earth's mantle and plays a crucial role in understanding geological processes, including plate tectonics and magma formation. Peridotite is often associated with ultramafic compositions, meaning it has a low silica content and high levels of magnesium and iron. It can also be a source of valuable minerals, such as diamonds and various metals.
