'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…

Dynamic subsidence of eastern Australia during the Cretaceous

by

Dynamic Subsidence of Eastern Australia Matthews et al (2011)During the Early Cretaceous Australia’s eastward passage over sinking subducted slabs induced widespread dynamic subsidence and formation of a large eperiogenic sea in the eastern interior. Despite evidence for convergence between Australia and the paleo-Pacific, the subduction zone location has been poorly constrained. Using coupled plate tectonic-mantle convection models, we test two end-member scenarios, one with subduction directly east of Australia’s reconstructed continental margin, and a second with subduction translated ~1000 km east, implying the existence of a back-arc basin. Our models incorporate a rheological model for the mantle and lithosphere, plate motions since 140 Ma and evolving plate boundaries. While mantle rheology affects the magnitude of surface vertical motions, timing of uplift and subsidence depends on plate boundary geometries and kinematics. … Read more…

High resolution reconstruction of the Central and Eastern Indian Ocean

by

Project Summary
Plate reconstruction models for the rifting and separation of Gondwanaland’s conjugate margins continue to be poorly constrained. We propose to develop a new, high-resolution plate model for the central and eastern Indian ocean by synthesizing old and new geological and geophysical data utilizing combined French and Australian advanced software for magnetic anomaly modeling and plate tectonic reconstructions. We will test alternative continental fit reconstruction hypotheses by using a variety of reconstructed data sets. Such a joint research is timely, as the Indian Ocean continental margins become the focus of intense oil and gas exploration.  … Read more…
