We present the input plate motion models and results from the study by Zahirovic et al. (2012) on the India-Eurasia collision using linked kinematic and geodynamic models.
Two end-member scenarios of the India-Eurasia collision were tested. The conventional model invokes long-lived Andean-style subduction along southern Eurasia until continental collision between a maximum extent Greater India and Lhasa at ~60 Ma. … Read more…

Congratulations to Maria Seton and her team who have been successful in a bid for ~$1M in ship time on the Southern Surveyor, the Australian Marine National Facility. Maria and her team will investigate the ‘Tectonic framework for the easternmost Coral Sea and northern extent of the Lord Howe hotspot’ during a ~3-week long cruise … Read more…
An Integrated Ocean Drilling (IODP) workshop on Indian Ocean Drilling to be held in late 2011 in Goa, India has just been approved, funded by $33,000 from IODP, and supported by the Australian IODP Office, which plans to send 15 Australians and Kiwis to the meeting, including EarthByte’s Dietmar Müller, and Stephen Gallagher (UMelb), Neville Exon (ANU), Richard Arculus (ANU), Mike Coffin (Tasmania) and Richard Wysoczanski (NZ, NIWA). The workshop is timed to suit an April 2012 drilling proposal submission deadline. … Read more…
Project Summary
Sea level has fluctuated by up to 300 m through geological time, creating vast sedimentary basins and associated natural resources. We will use Earth’s subduction history as imaged by seismic tomography to establish a subduction reference framework for the past 200 million years, tracking all tectonic plates in both latitude and longitude. 4D numerical mantle-plate tectonic simulations (3D plus time) will reconstruct how the recycling of old, cold oceanic plates into the mantle have influenced surface topography and sea-level change since the breakup of the supercontinent Pangaea. … Read more…
Reconstructing vanished oceans
We establish the locations and geometry of mid ocean ridges through time on the basis of marine magnetic anomaly identifications, geological information such as paleomagnetic data from terranes and microcontinents, especially in the Tethys Ocean, mid-oceanic ridge subduction events and the rules of plate tectonics. Based on a global set of tectonic plate rotations we construct a set of refined seafloor isochrons following the interpolation technique outlined by Müller et al. (1997; 2008) but including a multitude of additional data. … Read more…

Project Report
Understanding the initiation and processes governing subduction remains one of the greatest challenges in geodynamics. Subduction processes affect every aspect of the Earth system, from its control on the thermal and chemical state of the mantle, to its recycling of oceanic lithosphere, sediments, water and volatiles, to its affect on the atmosphere, hydrosphere, biosphere and solid Earth through earthquakes and volcanic eruptions. Moreover, subduction is generally agreed to be one of the primary driving forces of plate tectonics and mantle convection through slab pull and the addition of raw materials into the mantle. … Read more…
Project Summary
Data from three recent cruises on N.O. L’Atalante are used in collaboration with AGSO to use backscatter and bathymetry data for seafloor classification, and to reconstruct the tectonic and sedimentary history of selected areas, also based on 3.5 kHz, seismic reflection, gravity and magnetic data.
