A teleseismic travel time residual map of the Australian continent

Teleseismic travel time residuals for 43 seismic observatories and 6 networks of portable seismographs have been combined to produce a contour map of residuals for the Australian continent. Travel times to the shield regions of central and western Australia are low compared with average global travel times, indicating relatively high velocities in the upper mantle. The lowest times occur in the Archaean shield regions of Western Australia, the Proterozoic terranes in central Australia and the Gawler Block in South Australia, where heat flow is generally below world average. The residuals become progressively higher (arrival times later) towards the southeast, and the largest residuals are in Tasmania. The positive residuals indicate low velocities in the upper mantle, consistent with the predicted low velocity layer in the upper mantle under southeastern Australia, and higher observed heat flow.
