摘要：

The geological-geophysical studies carried out in the western part of the Pacific Ocean by the State Research Center "Yuzhmorgeologiya" during cruises of the R/V "Gelendzhik" in 2002-2004 yielded new data on the relief of the Gramberg Guyot and its constituting rocks, which appeared to be Early Cretaceous to Pleistocene in age. The analysis of macro- and microfaunal remains in sedimentary rocks made it possible to define the transgressive phases in the development of seamounts (the Cenomanian-Turonian, Late Campanian-Maastrichtian, and Late Cenozoic). The geological development of the Gramberg Guyot is compared with that of other similar structures of the Magellan Seamounts.
