Multi-element soil standard OREAS 45P was prepared from a sample of ferruginous soil, containing anomalous levels of precious and base metals, and a barren soil sample. The anomalous sample was obtained from soil developed over a Ni-Cu-PGE mineralised contact between gabbro and pyroxenite the Southern Murchison region of Western Australia while the barren sample was taken from an in situ layer of mature soil developed over early Tertiary olivine basalt in outer eastern Melbourne, Victoria, Australia.
