Asteroid impact connections of crustal evolution
Advances in isotopic age determinations increasingly point to the episodic nature of the evolution of lithosphere and crust, and in this paper well-documented field and geochemical evidence is to be reviewed, which indicates that at least some of these episodes were associated with large asteroid impacts. Observed overlaps between early Precambrian impacts (~3.47, ~2.63, ~2.56, ~2.48, ~2.023 Ga (Vredefort) and 1.85 Ga (Sudbury)) and isotopic age frequency peaks, defined within age errors, while...[Show more]
