%X Venus' mean surface age suggests that there may have extensive resurfacing of Venus prior to that epoch.Such global resurfacing is relative with the thermal evolution in the interior.Base on the properties and parameters of the Venus and the theory of mantle convection,we calculate the thermal evolution history of Venus.The results show that Venus' thermal evolution is a non-monotonic cooling process.In this process,Venus' mantle convection displays an overturn with a quasi-periodicity.Because of the different parameters,the stales of mantle overturn may appear in three modes.The punctuated turn over and avalanche effect in phase transition layer may play a key role for the resurfacing and lithosphere foundered of Venus in 500 Ma intervals.
