| Abstract: | We determined Ag, Bi, Cd, Co, Cs, Ga, In, Se, Te, Tl and Zn in the 6 ureilite achondrites by neutron activation analysis. All 11 elements are depleted below Cl levels and their characteristic abundance pattern differs substantially from those of chondritic groups. Thus ureilites do not represent a simple mixture of volatile-rich chondrites with achondritic material but perhaps cosmochemically-fractionated achondritic material and a late ‘distillate’ of mobile elements. |
