dc.description.abstractThis study presents a high-resolution 3D Vs model of the crust and uppermost mantle in the southwest Australia, using ambient noise tomography with continuous data from SWAN (2020–23) and all available stations in the region. The results reveal significant lateral structural variations associated with regional tectonics. The thick Phanerozoic sediments of the Perth Basin characterized by slow materials and the old cratonic basement rocks of the Yilgarn Craton are characterized by fast velocities. Overall, these results are consistent with previous geological and geophysical knowledge but the model’s resolution is significantly enhanced. We also identified a new high-velocity anomaly along the western edge of the Yilgarn Craton east of the Darling Fault, offering new insights into the tectonic relationships between the Yilgarn Craton and its surrounding structures.en
