The Marcus Necker Rise has two geologically distinct parts: the western one is composed of the Marcus Wake seamounts and the eastern one of the Wake-Necker seamounts. The first contain differentiated alkali basaltoids, while the second show a distinctive prolonged and complicated history. The latter contain Early Cretaceous olivine basalts and Late Cretaceous alkali and hornblende basaltoids.
