| Abstract: | This paper simulated the pattern of mantle convection and its evolution process under the driven force from modern plate tectonic motion based on a 3-D mantle convection model and then analyzed the mantle mixture effect further.The results show four main characteritics of mantle mixture: 1) Degree of mantle mixture is mainly controlled by tectonic driven forces.2) The degree of material mixture in the upper mantle is higher than that in the lower mantle.About 80% elements in the upper mantle and 60% in the ... |
