The School of Geography, Earth and Environmental Sciences organises a regular series of research seminars throughout the academic year to which everyone is welcome to attend. Speakers - both external and internal to the University - will talk on topics related to all aspects of Earth Sciences.
Today's speaker is Louise Koornneef from the University of Plymouth.The Oman ophiolite is a focus for international research on the formation and evolution of oceanic lithosphere. This talk will address how geophysical magnetic methods may contribute to our understanding of the ophiolite. Field-based palaeomagnetic and magnetic fabric analyses provide evidence for successive phases of formation, deformation and alteration linked to processes of seafloor spreading and tectonic emplacement onto the Arabian continental margin. In particular, the nature and causes of an important remagnetisation event that accompanied obduction will be discussed.
