The mare material located in Ingenii and the surrounding craters is of the Upper Imbrian epoch.

The dark circular feature which dominates this mare is the crater Thomson (112 km diameter), with the overflow from Ingenii/Thomson directly to the east.

The light grey crater to the south of Mare Ingenii is Obruchev.

[2] Prior to formal naming in 1961 by the IAU,[1] the crater was known as Basin XIV.

[4] The mare contains the second instance of a lunar pit discovered on the Moon and one of several outside the Earth to date.
