Scientific paper

In the present numerical modeling study of the thermal evolution of Venus, the mantle is taken to be composed of independently convecting upper and lower mantles. A novel parameterization is used which takes into account recent numerical investigations in media with complex rheology. The parameters of the convecting planet in the asymptotic regime do not depend on initial conditions, and are ascertained analytically. Convection in the lower part of the crust is demonstrated to be involved in regions having specific crustal composition; heat transfer to the surface is primarily via advection by magmas that are produced by melting of the lower layers of the crust.
