Abstract Ab initio calculations in forsterite (Mg $$_2$$ 2 SiO $$_4$$ 4 ) are used to gain insight into the formation of point defects and incorporation of noble gases. We calculate the enthalpies of incorporation both at pre-existing vacancies in symmetrically non-equivalent sites. and at interstitial positions. At high pressure. https://www.jmannino.com/mega-pick-Royal-Nomadic-5413-Rug-Ivory-Black-limited-super/
