MnO content in weight percent (wt%) for all rock chip samples from the WAMEX near-surface geochemistry database. WAMEX geochemical data are derived from exploration and mining activities in Western Australia, and from a variety of sample media, including surface rock chips, stream sediments, soils, unconsolidated material from shallow drilling, and rock chip or core material from deeper drilling.

The layer shows MnO values via a 3 × 3 cell mean neighbourhood statistics raster. Cell resolution is 0.05º (~5 km). Areas in red indicate a higher value.
