[5][6] The feature was then named after the ancient Roman public festival of Feralia, where citizens would place offerings at the tombs of the dead.

[7]: 91 [2]: 116  The surrounding cratered highlands likely represent ejecta blasted out by the impact event(s) that created Feralia Planitia.

[2]: 116–118  However, a precise date for Feralia Planitia's formation cannot be determined through crater counting, as the basin underwent a resurfacing event roughly 3.62 billion years ago.

[7]: 99  Feralia Planitia's surface is partially composed of eucrites, a type of basaltic rock containing anorthite, calcium-poor pyroxene, and augite.

This is in contrast to the older northern and northeastern highlands, whose mineralogy is dominated by howardite, a mixture of eucrite and diogenite.
