Crushed rock-water experimental data investigating the role of temperature in generating hydrogen and hydrogen peroxide from silicate rocks (NERC Grants NE/W005506/1, NE/S001670/1)

The data was generated from a range of laboratory experiments where a range of silicate rocks (granite, basalt, peridotite) were crushed in oxygen-free conditions, deoxygenated water added, and the generation of hydrogen gas and hydrogen peroxide followed over a week. Results were compared to rock-free controls. The data was collected to provide insight into the production of oxidants (such as hydrogen peroxide) along tectonically active regions of the subsurface, and how the oxidants might influence subsurface microbiology.
