Fig. 1

Gravity image of Australia, showing the main crustal elements. The Musgrave Province is located on the boundary between the Central and South Australian Cratons. Low gravity regions are shown in blue and high gravity regions in red. The new Musgrave Province MT sites described in this study are shown as triangles. All regional deep seismic traverses intersecting the Musgrave Province are shown as red lines, with seismic line names provided for those traverses referred to later in the text. All MT profiles intersecting the Musgrave Province are coincident with deep seismic traverses. The region used for Fig. 2 is marked by the black bounding box
