Abstract
The work aims to present new biostratigraphic data on Govorov, Vulkanolog, and Kocebu guyots of the western branch of the Magellan Seamounts (NW Pacific). The data were obtained during the voyage of R/V Gelendzhik in 2014. Analysis of the paleontological data on planktonic foraminifers, radiolarians, and corals allows us to distinguish several stratigraphic levels, ranging from Early Cretaceous to Pleistocene in age, which define the stages of geological development of the studied area. Based on the representative material on the planktonic foraminifers from layer I-2 of the ore crusts on Govorov guyot, it is established that this layer was deposited in the narrow age interval of 40.0–40.5 Ma. The data obtained clearly indicate the connection of the crust ore genesis on the seamounts with regional paleoceanic events.
