Anomalous lithosphere beneath the Proterozoic of western and central Australia: A record of continental collision and intraplate deformation?
A new surface wave seismic tomography model of Australia is presented which provides a means of investigating the lithospheric structure beneath the Proterozoic regions in the west, north and centre of the continent with improved resolution and reliability. The dominant feature of the model is a region of low seismic wavespeeds in the uppermost mantle, at approximately 75 km depth, beneath central Australia. The zone of slow wavespeeds is underlain by a region of fast wavespeeds, more typical...[Show more]
