Abstract: Lunar meteorites are the rock sample of the Moon that were experienced the shock event by asteroids and splashed away from it. Since the first lunar meteorites (ALHA 81005) was discovered and identified in 1979, there is the collection of 136 lunar meteorites. The Apollo and Luna projects returned 382 kg lunar samples, because the collection sites are very limited, so lunar meteorites are still the important supplementary to get insight of the composition and evolution history of the Moon. Except for the small amount of unbrecciated crystalline rocks, the majority of lunar meteorites are breccias which consist mainly of high land anorthositic breccias, mare basaltic breccias and the mingled breccias. According to petrographic analyses, especially clasts, lunar meteorites contain the variety of clasts as anorthosites, basalts, gabbros, troctolites, norites and KREEP rocks. There are more and more KREEP components found in lunar meteorites, in which the VHK KREEP clasts in SaU 169 may represent the urKREEP magma, and these KREEP components will provide the important information of the KREEP origin. Some works indicate that there are 6 launching pairs identified and 9 possible launching sites from the Moon. And the discovery of the lunar symplectites has the significance of the shock metamorphism on the lunar surface. Furthermore, the isotopic ages and the composition of noble gases not only provide the important information of the processions of crystallization of lunar rocks and the formation of lunar crust, but also get insight of the history of shock events on the lunar surface.

Key words: Lunar meteorites, KREEP rocks, KREEP, launching pair, launching sites
