OREAS 682
SKU: 682
OREAS 682 is a platinum group element (PGE) ore certified reference material
(CRM) prepared and certified by Ore Research & Exploration Pty Ltd. OREAS
682 has been prepared from PGE ores blended with barren gabbro-norite. The PGE
ores were sourced from the Merensky Reef and foot 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 682 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.
