b'Geophysics in the surveysNewsasthenosphere boundary (e.g., body and surface wave tomography, variably using teleseismic earthquakes, local earthquakes and the ambient noise field for illumination; receiver functions; noise autocorrelation; shear wave splitting; seismicity mapping). Furthermore, the contrasting sensitivities of seismic and MT data to factors including temperature, composition, fluids and melt will facilitate a more robust identification of primary indicators of mineral prospectivity such as metasomatism and fluid pathways.The AusArray SA stations will record passive seismic data continuously for 18 months in order to record sufficient earthquake and noise data for modelling purposes. Service runs will be at six month intervals. The raw seismic data will be housed on the AusPass passive seismic data server and the derived model outputs will be made available on SARIG.John ODonnell Geological Survey of South Australia John.ODonnell2@sa.gov.auReferencesGriffin W.
