| Abstract: | The gravity anomalies are mainly resulted from three factors: terrain gravity effects,mare basalts fill and Moho relief attraction. The terrain model GLTM 2 and the lunar gravity field model LP165 are used to estimate the crustal thickness between ±60° latitude of the nearside with the assumption that the thick of mare basalts fill is neglected. Additionally, a combinated crustal map is obtained. On the basis of the results the following conclusion can be drawn out: that the crustal thickness of the nearside of the Mon is between 15 km and 76 km, and the average is 48.6 km. It also shows that a generally thinner crust beneath the mare basins than regions around. |
