Laboratory experiments at extreme pressures and temperatures lead to precise measurements of the sound velocity of CaSiO3 perovskite which is one of the important constituent minerals in the Earth's mantle. The measurements suggested the accumulation of the subducted oceanic crust beneath the 660 km discontinuity.
