An abiotic source of Archean hydrogen peroxide and oxygen that pre-dates oxygenic photosynthesis

Hydrogen peroxide (H2O2) has been proposed as an electron donor for photosynthesis before water, however, the amount of H2O2 available on early Earth was thought to be limited. Here the authors propose a new abiotic pathway wherein abrasion of quartz surfaces would have provided enough H2O2.
