Ruthenium, rhodium, palladium, osmium, iridium and platinum (PGEs) and fort
y two other elements in two candidate geological Cretaceous-Tertiary bounda
ry clay reference materials taken from the "Fish Clay", Stevns Klint, Denma
rk, were determined by a combination of neutron activation analysis (NAA) c
onsisting of instrumental, epithermal and radiochemical NAA with or without
nickel sulfide fire assay preconcentration. The accuracy of the experiment
al values was assessed by the comparative analysis of the certified referen
ce materials.
