Abstract

Hydrogen is one of the important elements for the Earth’s evolution and structures since it strongly influences several physical and chemical properties of the mantle materials. Therefore, water storage capacity of the Earth’s interior have been well studied based on the phase relation in the MgO-SiO2-H2O system. Here we report experimental results on the phase transitions and dehydration temperatures of natural antigorite (endmember of serpentine group) up to 50 GPa using in-situ X-ray diffraction and maltianvil apparatus combined with sinter diamond anvils. Aluminium effect on the stability fields of serpentine was also examined using natural chlorite as a starting material.
