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 event]]s. 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.<ref name=Liu_Guo_2018/> Magnetic anomalies found in some Nectarian Period basins suggest that the Moon possessed a core [[Dynamo theory|dynamo]] [[magnetic field]] at that time.<ref name=Hood_2011/>
