OREAS 681
SKU: 681
OREAS 681 is a platinum group element (PGE) ore certified reference material
(CRM) prepared and certified by Ore Research & Exploration Pty Ltd. OREAS
681 has been prepared from PGE ores blended with barren gabbro-norite. The PGE
ores were sourced from the Merensky Reef and hanging wall of the Merensky Reef
of the Bushveld Complex, from sites owned and operated by Anglo American
Platinum, South Africa. The common minerals of economic importance within a
pegmatitic pyroxenite host are sulphides of iron, nickel, copper and alloys of
the PGE’s. The barren gabbro-norite was sourced from the Late Cambrian Black
Hill Norite Complex located 85km east of Adelaide, Australia. OREAS 681 is
one of a suite of five PGE ore CRMs ranging in 4E concentrations (4E = 4
elements; platinum (Pt), palladium (Pd), rhodium (Rh) and gold (Au)) from 0.82
to 6.1ppm.
