Abstract

Intracontinental basin formation reflects diverse tectonic and isostatic processes, posing challenges to extensional models and playing a pivotal role in understanding continental lithosphere evolution and optimising basin-hosted resource exploration. By utilising a holistic approach that integrates geophysical, petrological, geochemical, and petrophysical data, this research elucidates lithospheric architecture, basin formation, and subsidence evolution in Western Australia's Canning Basin region. The findings reveal variable lithospheric structure, composition, and origins of crust and mantle formation beneath the basin. Moreover, subsidence drivers are quantified, with sediment loading primarily influencing subsidence, followed by Large Igneous Province-related processes, thereby minimising the requirement for extensional subsidence.
