This plume is not recorded by seismotography and is not recorded in published plume and superplum catalogs. Data were obtained on the complex geometry of the superplume and its location, the penetration of the South American segment of the paleo-Pacific slab in the depths of the outer nucleus up to 4800 km (!), The depth of the formation and the explosive nature of the formation of superplum, its location in the torch of powerful heat flow, sweeping Southwest Pacific, West Antarctica and West Antarctica; the presence of a powerful nuclear thermal source in the southwestern Pacific Ocean. Linking the obtained model information with published data on megaregion and problems, the following main conclusions were obtained: 1) Ross' superplume formed in two different structural-dense lower-mantle-lithospheric situations: the southern part, near the Antarctic acraton and its subcratonic craton; the northern part, under the oceanic lithosphere; 2) Ross' superplum was formed as a result of a complex event triggered by a catastrophic seismic-magmatic strike into the undemantic structures of the Earth and the lithosphere caused by the sharp penetration of the Paleo-Pacific faint within the boundary of the outer core; 3) Ross' superplum event corresponds at the time of the 100 Ma event of the global reorganization of lithospheric structures, for which reason there is no agreement and which is not actually named Product Description popup.authors Bazylevska Marija S.
