Volcanic edifice on guyots of the Magellan Seamounts (Pacific Ocean)
Analysis of detailed bathymetric maps and phototelevision profilings on the surface of the Magellan Seamounts guyots revealed numerous cones and domes from the first hundreds of meters to 10 km in size, and from 30 m to 350 m in height. Age generations of these mesoforms have time intervals, such as Campanian-Maastrichtian, Late Palaeocene-Eocene, and Miocene. Formation of these complicated volcanic edifices is most likely caused by the late phases of volcanic activity associated with differentiation of magmatic melt. At the same time, the tectonic factor of their formation is well observed too. Miocene mesoforms on the Alba guyot lie on the intersection of sublatitudinal, submeridional, northeastern and northwestern lineaments.
