The distribution of mafic intrusions, gabbro, norite and anorthosite in Western Australia, coloured by the likelihood of their presence in these areas.

Legend	Description
Mafic intrusion dominant	Mafic intrusions are considered to be a dominant lithology within the polygon. There is a high probability of observing mafic intrusions, gabbro, norite or anorthosite in these areas
Mafic intrusion minor	Mafic intrusions are considered to be a minor lithology within the polygon. There is a lower probability of observing mafic intrusions, gabbro, norite or anorthosite in these areas
