Geochemistry, mineralogy and hydrogeochemisty of the Ambassador multi-element lignite deposit, Western Australia

Summary

Mid-Eocene lignites in palaeochannels at Mulga Rock in the SW Officer Basin are strongly enriched in a wide range of chemical elements, including base metals, rare earths and uranium at potential ore grades.

Two potential sources for the multi-element suite that forms the mineralisation of the organic matter at Mulga Rock are investigated.
