Summary:A quantitative relationship for the Hadean (>3800 m.y.) and early Archaean (3800-3400 m.y.) impact flux was derived from the lunar and terrestrial impact records, and the effects of impact-related processes on environments for abiogenesis estimated. The results indicate that if the deep marine mid-ocean ridge hydrothermal environment was suitable for abiogenesis, then this could have occurred between 4000 and 4200 m.y. ago, when at the Earth's surface this could have occurred from 3700 to 4000 m.y. ago.
