The structure of velocity mantle number of horizons under Phennoscandia according to seismic-tomography data
© T.A. Tsvetkova, I.V. Bugaenko, 2016
Seismic boundaries of the second kind have been distinguished under Phennoscandia according to three-dimensional P-velocity
model of the mantle and velocity number of horizons of the upper mantle and its transitional zone have been shown. Four velocity horizons
and corresponding seismic boundaries of the second kind have been distinguished. It has been shown that within the limits of the upper mantle
the market boundaries correspond to the known ones, distinguished by the super-long profiles: Phennolora, Quartz, Ruby and Svekalapka massif.
Seismic boundaries of the second kind of transitional zone have been marked.
Key words: seismic tomography, seismic boundaries of the second kind.
