Research Abstract

A new model : the dynamics of the Earth's mantle is driven by thermal/compositional heterogeneities existing in the upper/lower boundaries is proposed based on laboratory experiments on model mantle. The compositional heterogeneities control the global convective flow through actions of topography of the boundary layer. The thermal heterogeneities by localized heat source/heat transfer also control the global convective thermal field. The convective system in turn is responsible for generation of these heterogeneities. We have focused on how the interactions between these processes organize the system.
