An analytical scheme of radiochemical neutron activation for the sequential determination of ultra-trace rare earth elements (REEs) and highly siderophile elements (HSEs) in geological and cosmochemical samples is presented. Using this procedure, several selected elements of REEs and HSEs were successively determined for geological reference samples and olivine crystals separated from pallasite meteorites. Based on the data for geological reference samples, it was concluded that the procedure presented in this study could yield data usable for cosmochemical discussion of the genesis of pallasite meteorites.
