Nectarian
The Nectarian Period of the lunar geologic timescale was 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. The period ended with the formation of the Imbrium basin, which initiated the Imbrian Period. Magnetic anomalies found in some Nectarian Period basins suggest that the Moon possessed a core dynamo magnetic field at that time.
