Sutherland and collaborators proposed a geochemical scenario to argue that cyanosulfidic synthesis was a plausible process on the early Earth. Their scenario starts following a meteorite impact leads to the production of HCN and phosphate. The meteorite fragments also supply the necessary sulfide for the reaction. As ponds and lakes containing these reagents experience wet dry cycles, ferrocyanide, sodium, and potassium salts precipitate out of solution into evaporites, concentrating and storing reactants for future chemistry. These evaporites can then be thermally altered through additional impacts or geothermal heating, producing all necessary components for the proposed syntheses. Rain and runoff create streams that transport compounds along geochemical gradients, introducing new reactants along the way which causes new syntheses to occur. The streams are also exposed to ultraviolet radiation, providing energy for the reactions. The conditions described here support an evaporative lake or terrestrial hydrothermal pond scenario for the origin of life. The proposed geochemical scenario also relies on flow chemistry concepts to introduce new reactants throughout the process to cause additional chemical reactions and syntheses to occur.
