Geologic period, 3920 to 3850 million years ago From Wikipedia, the free encyclopedia
The Nectarian Period of the lunar geologic timescale runs from 3.920 billion years ago to 3.850 billion years ago. It is the period during which the Nectaris Basin and other major basins were formed by large impact events. Ejecta from Nectaris form the upper part of the densely cratered terrain found in lunar highlands.

Since little or no geological evidence on Earth exists from the time spanned by the Nectarian period of the Moon, the Nectarian has been used by at least one notable scientific work[1] as an unofficial subdivision of the terrestrial Hadean eon.
