The newly obtained Th map has revealed that two regions near the equator on the farside have the lowest Th abundances. We found that the variation of the Th abundance perfectly correlates with the crustal thickness in the farside and the southern nearside, and it could be a result of the crystallization of the lunar magma ocean.}, pages = {10--16}, title = {Lunar farside Th distribution measured by Kaguya gamma-ray spectrometer}, volume = {337/338}, year = {2012} }
