The relationship between craton margin geometry and deformation style in the North Australian Craton

This thesis investigates the influence of craton margin geometry on deformation styles at the edge of cratons, focusing on the North Australian Craton. Utilizing an integration of geophysical data interpretation, forward modelling, and analogue modelling, the study reveals distinct deformation patterns associated with inward and outward dipping craton margins. Inward-dipping margins show thin-skinned tectonics and interconnected fault zones, whereas outward-dipping margins exhibit crustal-penetrating faults. These findings enhance understanding of cratonic tectonic evolution and have significant implications for mineral exploration, demonstrating the critical role of craton margin geometry in governing deformation and mineralization processes in continental lithospheres.
