Geologic hydrogen accumulations are natural concentrations of molecular hydrogen (H2) generated within the Earth through processes such as water-rock reactions, radiolysis, and other geochemical mechanisms. Exploration focuses on identifying hydrogen-generating source rocks, migration pathways, and geologic traps capable of retaining commercially meaningful concentrations.
The following Elements and Minerals may be found in this Deposit Type.
No mineral relationship. Geologic hydrogen occurs as H2 gas in subsurface accumulations rather than as a mined mineral.
