Testing hotspot fixity in the Indian and Atlantic oceans

by

Project Summary
We have developed a novel interactive evolutionary inversion approach for computing absolute tectonic plate motions and their uncertainties based on hotspot tracks through time. We use a modified criterion of fit for inverting hotspot-track data, following an approach previously developed by Chang and co-workers for relative plate motions. Using this method, we derive covariance matrices for absolute plate rotations for the last 120 million years for the first time, using dated hotspot tracks in the Atlantic-Indian oceans. This represents a major advance in quantitatively constraining paleogeographic maps for the last 130 million years.  … Read more…

Earth’s magnetic field

by

Project Summary
The magnetic field measured by satellites has 3 distinct sources: the dynamo in the liquid core, magnetised rocks near the Earth’s surface, and the external, solar terrestrial environment. It is difficult to separate out the large-scale field (originates in the earth’s core) from the small-scale, permanent field (originates in the earth’s crust). This project aims to develop physical theories for the origin of each field to aid separation, accompanied by comparison with satellite data and iterative improvements. It is envisaged that this project will extend our knowledge of the core field to unprecedented fine resolution while establishing the larger scales of the crustal field.  … Read more…

The global fracture zone and magnetic lineation data base project

by

Project Summary
Plate kinematic models derive from the detailed identifications of conjugate magnetic isochron picks and fracture zones (FZ). These data form the foundation of all relative marine plate tectonic reconstructions and codify our understanding of Earth’s surface evolution since the Mesozoic. Furthermore, FZ traces have extensive uses in many other marine geophysical investigations such as studying the origins of transform fault offsets, identifying seamounts and isolating abyssal hill roughness within fracture zone provinces, examining predictions from competing thermal models of the lithosphere, and much more. Kinematic models also require temporal information and this dimension is provided by identification of key magnetic isochron boundaries from total field magnetic anomalies collected along ship tracks. … Read more…

Planet scale reorganisations of the plate-mantle system

Project Summary
Global climate change and shrinking resources have heightened our sense of dependence on the earth as a dynamic and complex system. This project aims to provide a unifying context for enhancing our understanding and appreciation of the workings of the inner earth and, in particular, its complex system behaviour during major tectonic events. … Read more…

‘Towards a unified East Gondwanaland reconstruction and its implications for Himalayan Orogeny’ wins funding

by

EarthByte’s Dietmar Müller, Joanne Whittaker and Ana Gibbons along with Gordon Lister and Lloyd White of the Research School of Earth Sciences at ANU, Canberra, have won funding for their project “Towards a unified East Gondwanaland reconstruction and its implications for Himalayan Orogeny” from the Australia-India Strategic Research Fund (AISRF). This project will involve a close collaboration with Yatheesh Vadakkeyakath, K.A. Kamesh Raju, G.C. Bhattacharya and S. Kiranmai of the National Institute of Oceanography in Goa, India. The project follows on from a successful French-Australian collaboration that unraveled a new high-resolution plate model of the Australia-Antarctica-India plate boundaries, while similar information was obtained for the India-Antarctica-Africa plate boundaries under two recently concluded Indo-French collaborations. … Read more…
