RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 15, ES3001, doi:10.2205/2015ES000552, 2015 ![]() Figure 6. Calculated structure of mantle convection with upper mantle viscosity $10^{21}$ Pa s, lower mantle viscosity $10^{22}$ Pa s, and density contrast at the $D"$ boundary 7%. (a) – initial state of convection with a supercontinent and velocity of the Pacific Plate 6 cm yr$^{-1}$. (b) – state of convection after 100 my with formation of two piles. (c) – similarly to (b), but at a higher plate velocity of 12 cm yr$^{-1}$. Copyright 2015 by the Geophysical Center RAS. Generated from LaTeX source by ELXpaper, v.1.3 software package. |
