摘 要：Iron-bearing bridgmanite （Mg,Fe） SiO with the orthorhombic perovskite-type structure is the predominant phase in the Earth’s lower ***,its fundamental physicochemical properties and thermal stability largely influence the geodynamic process of the inner *** pressure and temperature（P-T） experiments on the system MgSiO-FeSiO have been widely conducted under the high P-T conditions corresponding to the Earth’s lower mantle.
