主　　题：Porosity Thermal evolution Ferroan anorthosites 

摘      要：The lunar ferroan anorthosites,formed by plagioclase flotation from the crystallization of the lunar magma ocean,have an age span of over~200 ***,previous thermal models predicted a much shorter time *** propose that a much smaller thermal conductivity of anorthositic crust due to its high porosity may have delayed the solidification of the lunar magma *** thermal simulation results,using the thermal conductivity of porous lunar crust,show that crystallization of a 1000 km deep magma ocean could be prolonged to tens of millions of years,and up to 180 Ma under some extreme *** porous crust alone can’t explain the large crustal age span,*** circumstances must be taken into consideration,such as a thick lunar soil.
