Geochemistry and super(40)Ar- super(39)Ar geochronology of impact-melt clasts in feldspathic lunar meteorites: Implications for lunar bombardment history

Abstract- We studied 42 impact-melt clasts from lunar feldspathic regolith breccias MacAlpine Hills (MAC) 88105, Queen Alexandra Range (QUE) 93069, Dar al Gani (DaG) 262, and DaG 400 for texture, chemical composition, and/or chronology. Although the textures are similar to the impactmelt clasts iden...
