Probabilistic Shear-wave Velocity Models of the Crust and Shallow Lithosphere in Continental AreasThis project adimedto continue the 2018 project under user account pawey0112. A major task for 2019 was to apply a new tomographic inversion technique developed using the Pawsey resources in 2017 and 2018 (Yuan and Bodin, Tectonics, 2018) to develop high-resolution probabilistic shear-wave velocity models of the crust and shallow lithosphere in continental areas, under several funded projects through various funding agencies in Western Australia, China and the US. The models have direct impact in understanding mineral systems by directly mapping various components of the system: deep penetrating faults, suture zones. These features have important controls on the movement of metal-carrying magmas and brines in a variety of mineral systems. High resolution models of the continental crustal and lithosphere at various tectonic settings will also shed light onto better understanding the formation and subsequent evolution of continent crust through time

Not really a problem but the high priority model implemented this year is really good.
This project so far resulted in a published paper in Nature Communications, and a manuscript in revision which was submitted to Geochemistry, Geophysics, Geosystems. Resources from the Pawsey Centre is critical for obtaining the results which are computationally heavy.
