Velocity section of the upper mantle under the island arcs of the northern and western outlying parts of the Pacific Ocean
© V.V. Gordienko, L.Ya. Gordienko, 2015
We construct a velocity model of the upper mantle beneath the Island Arcs in the northern and western parts of the Pacific Ocean for the arrival
times of longitudinal seismic waves at seismic stations in this regions. Revealed anomalies may indicate a very young geosynclinal process.
Typical velocity model of the upper mantle of island arcs is fully consistent with the advection-polymorphic hypothesis deep processes.
Key words: island arcs, upper mantle, velocity models, geosynclinal process, recent magmatism.
