We investigate the thermal/impact histories of four HED meteorites: one cumulate eucrite (Lake Carnegie) two brecciated basaltic eucrites (Camel Donga, Millbillillie), one howardite (Old Homestead 003) and an anomalous basaltic achondrite (Deakin 010). We have measured eight convincing new 40Ar/39Ar ages for three HED meteorites. Laser incremental 40Ar/39Ar analyses of carefully separated small grains (
