The CSIRO mafic-ultramafic package includes whole-rock geochemical data and mineral chemistry data collected from CSIRO research projects from the mid-1980s to 2021. The data set includes over 7700 samples, primarily from the Archean of Western Australia, with a heavy bias towards komatiites and immediately associated rocks and nickel sulphide ores. Most of the data were collected as part of research projects related to the exploration of magmatic sulphide nickel-copper ore deposits. The data set also includes samples from mafic-ultramafic intrusive rocks in the Halls Creek and Albany-Fraser orogens.
