Carbonatite are of a great economic importance because this rocks contain valuable rare metals. At present tree models of geodynamic regime of carbonatites formation are actively develop. 1- the generation of carbonatite melts within the lithospheric mantle, 2- the close connection of carbonatites with the zones of orogenesis, 3- a large group of carbonatites links to deepseated mantle plumes. For the first time using the modern model of “absolute” paleotectonic reconstructions and large database was showed the general connection of Phanerozoic carbonatites to the large areas of low velocities of S‑waves located in the lower mantle — zones of the generation of deep mantle plumes.
