Mantle dynamics in Mars and Venus - Influence of an immobile lithosphere on three-dimensional mantle convectionThe manner of the mantle convection in planets with rigid lids, such as Venus and Mars, is investigated using a numerical method. The effect of the rigid upper boundary condition on mantle convection was examined by comparing the convection in planets with rigid lids with results for planets with shear stress-free upper surfaces. The results for convection in models of the mantles of Mars and Venus show that the cylindrical plume is the prominent form of upwelling as long as sufficient heat enters the mantle from the core.
