The breakup of the Pangea supercontinent in the last 200 million years has controlled the arrangement of continents, the opening and closure of oceanic gateways, and has influenced long-term climate and sea level. The eastern Tethyan region records long-term convergence between the Indo-Australian, Eurasian, and Pacific plates. This region has been dominated by subduction, leading to large volumes of subducted slabs in the mantle beneath Southeast Asia and northern Australia. These sinking slabs affect the long-wavelength topography of the region (namely, ‘dynamic topography’), leading to long-term flooding of these areas despite falling global sea levels since 30 million years ago. This talk will cover the approaches used in constructing plate tectonic reconstructions using the open-source community GPlates (www.gplates.org) platform, as well as methods that link the reconstructions to numerical models of mantle flow. The talk will be followed by a hands-on tutorial on how to install and use GPlates for your own research and teaching.
