Results of geological research carried out by V.I. Il'ichev Pacific Oceanological Institute (Far East Division of the Russian Academy of Sciences) and P.P. Shirshov Institute of Oceanology (Russian Academy of Sciences) on the submarine Vityaz Ridge during Cruise 37 of R/V Akademik Lavrentyev in 2005 are discussed. Various rocks composing the basement and the sedimentary cover of the ridge were dredged in three areas. Based on isotope geochronology, petrogeochemical, petrographic, and paleontological data and comparison with similar rocks available from the adjacent land and the Sea of Okhotsk, they are subdivided into several age complexes. Late Cretaceous, Eocene, Late Oligocene, Miocene, and Pliocene-Pleistocene complexes are defined among igneous rocks, while volcanogenic-sedimentary rocks are united into Late Cretaceous - Early Paleocene (Late Campanian - Danian), undivided Paleogene (Paleocene-Eocene?), Oligocene - Early Miocene, and Pliocene-Pleistocene complexes. Obtained data on age and formation settings of the defined complexes allowed to reconstruct geological evolution of the central Pacific slope of the Kurile Island arc.
