Researchers Explore the Water Locked in the Earth's Deep Interior

A research team led by Prof. ZHANG Feiwu from the IGCAS systematically investigated the incorporation mechanisms and elastic properties of hydrous Bridgmanite and post-Perovskite by performing first principles calculations at the conditions of lower mantle pressures and temperatures,.
The results indicated that the effect of hydration on the elastic wave velocities and moduli, especially the shear velocity and the shear modulus, was more noticeable in the Fe-bearin... DETAILS... MORE...
