Velocity divisibility of the mantle beneath the Ukrainian shield

Velocity divisibility of the mantle beneath the Ukrainian shield

Within the limits of three-dimensional Tailor approximation P-velocity model of the mantle under the Ukrainian shield it has been shown that the mantle under it, according to its velocity characteristics, can be subdivided into 3 domains: the Western, the Central and the Eastern ones. The Volynian a...
