AusArray: Imaging the lithospheric mantle using body-wave tomography
Mineral deposits are the products of lithospheric-scale processes. Imaging the structure and composition of the lithosphere is therefore essential to better understand these systems, and to efficiently target mineral exploration. Seismic techniques have unique sensitivity to velocity variations in the lithosphere and mantle, and are therefore the primary means available for imaging these structures. Here, we present the first stage of Geoscience Australia's passive seismic imaging project (AusArray), developed in the Exploring for the Future program. This includes generation of compressional (P) and shear (S) body-wave tomographic imaging models. Our results, on a continental scale, are broadly consistent with a priori expectations for regional lithospheric structure and the results of previously published studies. However, we also demonstrate the ability to resolve detailed features of the Australian lithospheric mantle underneath the dense seismic deployments of AusArray. Contrasting P- and S-wave velocity trends within the Tennant Creek – Mount Isa region suggest that the lithospheric root may have undergone melt-related alteration. This complements other studies, which point towards high prospectivity for iron oxide–copper–gold mineralisation in the region.

-
The HiPerSeis software library was used to combine three global and two regional earthquake catalogues, pre-process continuous waveform data from seismometers, perform quality assurance/quality control, and generate P- and S-phase travel-time arrival picks. These were then used within a linearised inversion scheme, with ray tracing employed as the basis to map relative arrival time into mantle compressional- and shear-velocity structure beneath the Australian plate.
