Scientific paper

In order to constraint on the possible mineral composition, thermal structure of the Earth's interior, equation of state, sound velocity and shock temperature and melting measurements of perovskite-enstatite (Mg, Fe)SiO3 and porous iron, were performed through shock wave experiments. A fully new mineralogical model of the lower mantle is proposed The temperature of the core-mantle boundary (core side) is 3750(plus-or-minus150) K, the inner-outer core boundary is 5350(plus-or-minus150) K, and the center of the core is 5500(plus-or-minus150) K.
