Abstract
So far, volatiles in the terrestrial atmosphere and oceans have been considered to have been originated due to degassing from the Earth's interior during early period of the Earth's history. In recent years, it has been proposed that such volatiles including water might have been transferred to the Earth by late veneer which had been considered to explain PGEs pattern in the mantle and some other signatures. So far, noble gas isotope signatures have been explained based on the degassing from the Earth's interior and the effect of late veneer has not been well examined. In this talk, I will discuss the effect of late veneer(s) to the noble gas signatures.
