Behavior of Hydrogen in Crystal Structures of Slab and Mantle Minerals

Abstract

This paper reviewed the hydrogen incorporations in crystal structures of some slab and mantle minerals based on the recent author’s and the group’s studies. The topics included 1) hydrogen positions in the crystal structures of Mg₂SiO₄ polymorphs, humite minerals and DHMS phases, and 2) the effects of hydrogen on the physical properties of these minerals.
