How responsive are continental interiors to the geodynamic evolution of plate margins? An Australian case study. The outcomes of this project will advance our understanding of the evolution and dynamics of the Australian plate by improving knowledge of the way plate driving forces shaped the continental interior. This will lead to a refinement of existing geological models describing the history of the Australian continent, and will provide a valuable backdrop for the current focus on the cont ....How responsive are continental interiors to the geodynamic evolution of plate margins? An Australian case study. The outcomes of this project will advance our understanding of the evolution and dynamics of the Australian plate by improving knowledge of the way plate driving forces shaped the continental interior. This will lead to a refinement of existing geological models describing the history of the Australian continent, and will provide a valuable backdrop for the current focus on the contemporary state of the Australian plate. The study will also provide a framework for petroleum exploration models in the central Australian basins, since they rely crucially on the thermal and structural datasets that will be produced in this project.Read moreRead less
Thermal regimes, flexure and duration: establishing the framework for intracratonic orogeny in central Australia. Intracratonic orogeny is a confronting phenomena because it contradicts the plate tectonic paradigm, which highlights the apparently rigidity of the lithospheric plates. Central Australia contains an exceptional record of intracratonic orogeny, expressed by the formation of the Petermann and Alice Springs orogens. This project will quantify the duration, and thermal conditions assoc ....Thermal regimes, flexure and duration: establishing the framework for intracratonic orogeny in central Australia. Intracratonic orogeny is a confronting phenomena because it contradicts the plate tectonic paradigm, which highlights the apparently rigidity of the lithospheric plates. Central Australia contains an exceptional record of intracratonic orogeny, expressed by the formation of the Petermann and Alice Springs orogens. This project will quantify the duration, and thermal conditions associated with the comparatively poorly known Petermann Orogen. Given the importance of intracratonic deformation in shaping the lithospheric architecture of central Australia, understanding the history of the Petermann Orogeny is essential to developing models that describe the evolution of the Australian continent, and continental interiors in general.Read moreRead less
