Velocity typing the middle and lower mantle of Europe
© I.V. Bugaenko, L.N. Zaets, T.A. Tsvetkova, 2015
We used 3D Ð-velocity model of the mantle of Europe. The model was constructed by V.S. Geyko's proposed method of Teylor
approximate solution of seismic tomography. The velocity structure of the middle and lower mantle of the velocity model was analyzed.
Four types of mantle have been allocated under Europe: the stable mantle, the activated mantle, the mantle unsteady on an activated type,
the unsteady mantle on a stable type.
Key words: seismotomography, Ð-velocity model, middle and lower mantle, typifi cation, Europe.
