What is this layer?
MnO content in weight percent (wt%) for all samples from the Geoscience Australia OZCHEM (WA subset) geochemistry database. Most of the samples analysed and here included from Western Australia are surface samples, but some are subsurface specimens from drillholes (sample locations are projected to the drillhole collar).
The layer shows samples that have been analysed for MnO via a 3 × 3 cell mean neighbourhood statistics raster. Cell resolution is 0.05º (~5 km). Areas in red indicate a higher value.
