serpentinisation

Others think it much more likely the methane is produced by geological activity, from active Martian volcanoes or from a geochemical process called serpentinisation.

If the methane is produced by geological activity, it could either originate from active Martian volcanoes or from a process called serpentinisation.

But during the formation and uplift of mountain ranges, some mantle rock can be brought close to the surface, where it can react with water in a process called serpentinisation.

The company’s working theory is that hydrogen is generated when water from underground aquifers seeps into the iron-rich mantle rock of the Midcontinent rift and reacts with the metal in a process called serpentinisation.

One way to do this would be to go deeper, where temperatures are higher, as this enhances serpentinisation, says Gelencsér.

Water reacts with certain rock types to form hydrogen in a process called serpentinisation, which is the source of a lot of natural hydrogen.
