The Thomson Orogen, which is located in central Queensland and north-western NSW, is the least understood component of the Tasmanides. In particular, it is unclear why the southern boundary of the Thomson Orogen is oriented ~E-W, perpendicular to the dominant ~N-S orientation of the Tasmanides. Rashed Abdullah's PhD project aims to unravel the 3D geometry of the Thomson Orogen, to explain its structural relationships with other components of the Tasmanides, and to interpret the geodynamic and tectonic processes that led the formation of the ~E-W southern Thomson boundary. Understanding the origin of the curvilinear ~E-W structures will provide vital information on the Paleozoic tectonic evolution of the Australian continent and may offer new ideas in global tectonics.
