"How to
proceed:
"
"Gather
information about the convective regime i.e. material properties, boundary
conditions, e.t.c.
"
"=> have a
model of convection in the Earth mantle and understand the mixing properties
"
"=> feed
information derived from the geochemical investigations back into the model and try
to refine it until it fullfills geochemical constrains
"
" => the SUPER-MODEL
