What is Olivine?
Olivine is a group name for minerals and refers to a group of silicate minerals, usually containing magnesium and iron. These minerals, with the chemical formula (Mg, Fe)2SiO4, are found in volcanic rocks and basaltic rocks.
Olivine minerals usually have a greenish color, but their color can vary depending on the magnesium and iron content. Crystallized at high temperatures, these minerals usually have a composition dominated by magnesium.
Olivine is a mineral usually found in magma and is an important component of the Earth’s crust. These minerals are brought to the surface during volcanic eruptions and lava flows. They have an important role in the fields of mineralogy and petrology and can help in understanding some geological processes.
