Reassessing the role of magnetite during natural hydrogen generation

Frontiers in Earth Science, 2023
Interactions between water and ferrous rocks are known to generate natural H2 in oceanic and continental domains via the oxidation of iron. Such generation has been mainly investigated through the alteration of Fe2+-silicate and some Fe2+-carbonates.
