(Table 2) Absolute age of Magellan Seamount Guyots

This paper generalizes both original data and all available materials obtained by home and foreign researchers when studying guyots of the Magellan seamounts. The Magellan seamounts represent an extended arc-like chain of seamounts, mainly guyots within the middle part of the East-Mariana Trough. The guyots rise above the relatively flat floor of the East-Mariana Trough with depths about 5500-6000 m to the height up to 4500-4800 m and reach depth level from 1300 to 1200 m. In 1980s-1990s the Magellan seamounts become objects of permanent studies for both home and foreign researchers. First of all it is connected with the fact that considerable accumulations of Fe/Mn crusts and nodules were found at slopes and tops of the Magellan seamounts. Though having some similar features, the guyots of the Magellan seamounts differ considerably in their geological structure, time of formation and duration of volcanic activity. They were studied rather non-uniformly. The Ita-Maitai, Dalmorgeo, Roskomnedra, Vulkanolog, TIG, Hemler guyots and the Himu seamount were studied in detail, while the Nakhodka, IMGiG, TOI, DVGI guyots and the D-4 and Golden Dragonseamounts are less studied. The MA-3, MA-4, MA-10, MA-11, MA-27, MA-29, MA-31 and MA-38 guyots are very poorly studied.
