| Summary: | <!--!introduction!--> The geology of Antarctica is formed from cratons, accreted terranes from multiple supercontinental cycles, and ongoing tectonism and glaciation. It would be a mistake to assume that the subglacial continent is geologically less complex than any other part of the world. Geophysical data and the observed interaction between the solid Earth and the ice sheet suggest several distinct geological regions in the interior. Antarctica's margins have been affiliated with geological observations in adjoint Gondwana neighbours, and those projections identify Antarctica as a hub in the supercontinent cycle rather than a snowbank at the margin of the map. However, producing a robust tectonic map of the interior is challenging, as existing datasets and models are inconsistent and the interpretations ambiguous. We map the tectonic domains of the Antarctic continent by applying a similarity approach. From multivariate observables in other continents, we calculate the most similar tectonic setting ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
