This is a chemical formula for a silicate mineral called enstatite, which has the chemical composition Mg2SiO4. It is a common mineral in the Earth's mantle and is part of the pyroxene group of minerals. The presence of NaAlSi3O8 in the formula suggests the possible presence of feldspar in the mineral composition as well.
