OREAS 25b
SKU: 25b
OREAS 25b was prepared from a blend of in situ layers of mature soils
developed over early tertiary tholeiitic basalt in outer eastern Melbourne,
Victoria, Australia and colluvium sourced from the Ettamogah region of NSW,
Australia. Fifteen laboratories participated in the program to characterise the
elements reported below. The following methods were employed:
Au, Pt and Pd by low level fire assay with ICP-OES, MS or AAS finish
Lithium borate fusion for full suite X-ray fluorescence including LOI at
1000 degrees
Sodium peroxide fusion or lithium borate fusion for full suite ICP-OES and
ICP-MS
4-acid (HF-HNO3-HClO4-HCl) digestion for full ICP-OES and ICP-MS elemental
suites
Aqua regia digestion for full ICP-OES and ICP-MS elemental suites
Infrared combustion furnace for Total C and S
