OREAS 465 is one of six MMCRMs ranging TREO 0.53 – 9.88% and contains 100 certified values (and 50 indicative values) including REE’s, majors and traces by fusion XRF, fusion ICP and 4-acid digestion.
A summary of the mineralogy and supergene enrichment processes that operated in the host lateritic rocks is given in the Certificates of Analysis. Two ‘Datapack’ files are provided. The ‘Elemental’ version contains all Certified Values in their elemental form while the other Datapack shows some of the Certified Values in oxide format. This includes the fusion XRF group and the majors and REE’s (and a few other associated metals) in the fusion ICP group.
