Two colour maps sheets at 1:5 million, 1:7.5 million and 1:15 million scale show the continental extent of Proterozoic Large Igneous Provinces and other mafic-ultramafic magmatic events, and their relationships to the Australian Crustal Elements. A time series shows the evolution of location controls on mafic-ultramafic magmatism from 2500-500 Ma. Polugons and linework are derived, with modifications, from the 'Map of Australian Proterozoic mafic-ultramafic magmatic events' (Hoatson, Claoue-Long & Jaireth 2008).
