Isotopic geochronology is one of the important tools to study formation and evolution of the Moon. The available dating techniques applied to the lunar rocks and meteorites include K-Ar,Ar-Ar,Rb-Sr,Sm-Nd,Lu-Hf,Re-Os,Pb-Pb and U-Pb,etc. According to the data obtained by these methods,the highland rocks were mostly formed during 4.5-3.8 Ga; whereas the mare basalts,mainly erupted in the period of 3.8-3.1 Ga,are a little younger than that of the highland rocks. This conclusion,combined with the data obtained from the short-lived Hf-W and Sm-Nd isotopic systematics,suggests that the Moon was initially accreted at 4.5 Ga,followed by development of the global lunar magma ocean (LMO). The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However,the mafic minerals,coevally crystallized with the plagioclase,sank to the base of the LMO due to their high density,and made up the main part of the lunar mantle,which served as the source during later mare basaltic magmatism. In addition,a comprehensive overview is given to the geochronologic study of the lunar rocks to date,and propose some key technical points which should be developed in the future.
