Greenbushes laterite geochemistry orientation study. LabWest reanalysis 2018 geochemical data.

Geochemical analyses of lateritic cover about the Greenbushes mineralised pegmatite deposit and surrounding terrain. Original analyses were done in the early 1980s. Samples are dominantly of lateritic duricrust (nodular & pisolitic) and loose lateritic pisoliths, lateritic nodules as well as some near-surface bedrock. Major, minor and many trace elements were analysed and are listed.

Results revealed a large (15 km by 30 km), coincident multi-element geochemical halo in lateritic residuum centred on the world class mineralised rare metal pegmatite system. Key elements in the halo are Sn, As, Sb, Nb, Ta, Li, B, Be, Bi ...

Pulps which had been used for the original analyses were retrieved from the CSIRO Collection for reanalysis in December 2017 by LABWEST Western Australia providing updated analytical methods, more elements and generally lower limits of detection.
