The probable continuum between emplacement of plutons and mare volcanism in lunar crustal evolution [PDF]

open access: yes
A scenario for the formation of the Moon is advanced and is argued to be consistent with both known data and the leading hypothesis regarding the formation of the Moon. It is concluded that, although the volume of mare basalts is estimated to be only 0.1
