Closed ATM View - GA2021/279
Inorganic Geochemistry Analysis
Canberra, Sydney, Melbourne, Adelaide, Perth, Brisbane, Darwin, Hobart
As part of the extension of the Exploring for the Future (EFTF) program, GA has identified target areas for mineral, energy and groundwater studies. These studies are aimed at exploring Australia’s resource potential and boosting investment. A key component of this program is directed at improving our understanding of the geochemistry of the Australian continent.
As part of this work inorganic geochemistry data is required in order to achieve project goals. The work will require whole rock analysis, XRF for major elements and ICP-MS analysis of the fused glass bead for total contents. In addition there is requirement for a small batch of samples to also be analysed using solution ICP-MS of four acid digested samples. Additional analyses may be included and are outlined in the desirable analytical services.
Supplied input
Up to 24,000 (with up to 11,000 prior to contract extensions) rock and regolith samples (provided as prepared rock powders)
Deliverables
The Supplier will carry out inorganic major and trace analyses and reporting on up to 24,000 (with up to 11,000 prior to contract extensions) rock and regolith samples.
Essential analytical services will include:
•Elemental analysis of 62 elements (including 11 major elements as oxides and 51 trace elements, including rare earth elements) on up to 11,000 rock and regolith samples by XRF and ICP-MS using the fused glass disc. Additional samples may require alternative digestion techniques such as four acid and aqua regia digestion.
oThe major elements, reported as oxide percent by weight percent, include: SiO2, Al2O3, CaO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SO3, TiO2. The desired trace elements, including rare earth elements, reported as parts per million are: Ag, As, Ba, Be, Bi, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, In, La, Lu, Mn, Mo, Nb, Nd, Ni, Pb, Pr, Rb, Re, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr. The precision error for the major element data and trace element data should be better than 15%. If particular trace elements cannot be analysed this should be specified in the response to the tender.
•C, S – by Infrared, e.g., Carbon Sulphur analyser
