Abstract
Плотностные и реологические неоднородности мантии активных океанических окраин западного сектора Тихого океана и зоны Курильского глубоководного желоба
Highlights
Recent knowledge of active oceanic margins with using of geodynamic simulations under constraints of gravity anomalies is analysed in this work
The mantle viscosity varies in the range from maximum 1023 Pa s within the lower layers to 1019 Pa s inside the low viscosity wedge
The geoid anomalies are the significant additional informative source for investigation of the deep structure of the transition zones
Summary
Recent knowledge of active oceanic margins with using of geodynamic simulations under constraints of gravity anomalies is analysed in this work. The aim of the analytical review is estimation of density and viscosity distribution in the subduction zones of the well investigated deep trenches of Pacific Ocean.
