PANGAEA, https://doi.org/10.1594/PANGAEA.755169, Supplement to: Rudnik, GB; Matveenkov, VV (1978): Composition and stages of development of volcanic rocks in the Marcus-Necker Ridge. Oceanology, 18(3), 319-322 Abstract: 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.
