Water plays an extremely important role in the physical properties of materials in the Earth's interior. An understanding of hydrogen in the NAMS at the atomic level is the fundamental for the development of dynamic models in the Earth's mantle. Previous studies showed that the minerals with faster Mg diffusivities seem to have higher hydrogen solubility. In this study, the relationship of hydrogen solubility and the cation diffusion coefficients in the main minerals of the Earth was studied. Mg diffusion coefficients in olivine, wadsleyite, ringwoodite and perovskite were chosen. Si diffusion in stishovite was used because there is no Mg in it. The hydrogen solubility data were expressed by molar ratio and calculated from water content data by weight. We selected the larger water content data in previous studies that may be close to the hydrogen solublity of minerals. The ratio of the square root of cation different coefficients …
