  The purpose of this work is to compare kinematics of small-scale current
vortices located near the core-mantle boundary with high-speed anomalies of
seismic wave velocity in the lowest mantle asso-ciated with the subduction
zones. The small-scale vortex paths were early obtained by the authors in the
frame of the macro model of the main geomagnetic field sources. Two sources
were chosen whose kine-matics are characterized by the complete absence of the
western drift and whose paths have a very com-plex shape. Both sources are
located in the vicinity of the subduction zones characterized by the extensive
coherent regions with increased speed of seismic waves in the lowest mantle.
One of them is geographically located near the western coast of Canada and the
second one is located in the vicinity of Sumatra. For this study we used the
global models of the heterogeneities of seismic wave velocity. It was obtained
that the complex trajectories of the vortices is fully consistent with the
high-speed anomalies of seismic wave velocity in the lowest mantle. It can be
assumed that mixing up with the matter of the lowest mantle, the substance of
the liquid core rises along the lowest mantle channel and promotes its further
increase. In addition, the volume of oceanic crust, subducted millions of years
ago, turned out to be sufficient to penetrate into the liquid core, forming the
complex shape restrictions for free circulation of the core liquid.
