Abstract

Neutron activation analysis after preconcentration of nickel sulfide fire assay was used in measurement of Ru, Ph, Pd, Os, Ir, Pt (i.e. PGE elements) and Au concentrations for basalt, mantle and granulite xenoliths in Hannuoba. The chondrite- and primitive mantle-normalized PGE patterns generally exhibit flat (for Iherzolite), negative slope (for harzburgite), and positive slope (for basic granulite and basalt). In addition, strong Ir negative anomaly occurs in basalt and granulite xenolith, and little negative anomaly also exists in Iherzolite xenolith in Hannuoba.
