PHOSPHORUS REDOX CHEMISTRY THROUGH TIME
This study has been expanded to include a number of other Archean rocks, finding prevalent phosphite in many older rock samples. Additionally, the production of phosphite from impact has been shown by chemical stratigraphy of a late Archean impact layer. Finally, phosphite has been detected in recent water samples, and is likely linked to microbiological processing of P compounds. These results suggest a long history for P redox chemistry occurring throughout the history of the earth, with potential impact on the development of life through time.
