Role of hydrogen and proton transportation in Earth’s deep mantle

Hydrogen (H) is the most abundant element in the known universe, and on the Earth’s surface it bonds with oxygen to form water, which is a distinguishing feature of this planet. In the Earth’s deep mantle, H is stored hydroxyl (OH−) in hydrous or nominally anhydrous minerals. Despite its ubiquity on...
