Neutron activation analyses of Ag, Au, Bi, Cd, Co, Cs, Ga, In, Rb, Sb, Se, Te, Tl, U and Zn in whole-rock, melted and unmelted regolith samples of Yamato-82192 reveals a lunar highlands origin plus meteorite admixture, 2.4±0.8% Cl-equivalent for micrometeorites and ancient impact component. A small but real amount of mobile element loss occurred during the shock-melting episode that formed Y-82192. Differences in trace element and other trends indicate pronounced differences in the thermal histories of the parent regoliths of Allan Hills A81005 and Y-791197 and -82192 so that each must have been produced by a separate impact on the Moon.
