Forsterite is a mineral that belongs to the olivine group, primarily composed of magnesium silicate. Its chemical formula is Mg2SiO4, and it is known for its green to yellow-green color. Forsterite is commonly found in igneous rocks and is a significant component of the Earth's mantle, making it important for geological studies. This mineral is often used in various industrial applications, including ceramics and refractory materials, due to its high melting point and durability. Forsterite can also be found in some meteorites, providing insights into the formation of the solar system and the conditions present in space.
