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.diegojavierfares.com/quick-offer-Little-Ollie-174-Dwarf-Olive-Monrovia-super-sale/
