The East African Institute for Fundamental Research (EAIFR) and the International Centre for Theoretical Physics (ICTP) wish to inform those who may be interested of a GEO@EAIFR webinar. This seminar will take place on September 06, 2022 and will be broadcast live on ZOOM. It will also be recorded and later posted on the ICTP-EAIFR YouTube channel, where one can find the previous recorded GEO@EAIFR webinars. Below all the details:

Speaker: Professor Jeroen van Hunen, Department of Earth Sciences, Durham University, UK

All are very welcome.

Biography:

Professor Jeroen van Hunen is a Professor in Computational Geoscience at Durham University in the United Kingdom. He studied geophysics at Utrecht University, the Netherlands, from where he also obtained his PhD. In 2002, he moved to the University of Boulder, USA for a postdoctoral position, and in 2004 to ETH, Switzerland as a junior researcher. In 2006, he moved to Durham. His research focusses on a range of fluid dynamical applications in Earth sciences, from large-scale geodynamics (including subduction and collision systems, and plate-mantle interaction) to geothermal energy. One particular focus has been the dynamics and evolution of the early Earth. 

Abstract:

Cratons are the oldest, coldest and thickest parts of the Earth’s lithosphere. These cratons have unique structures and compositions, and are unlike typical younger lithosphere. So how were these ancient, and apparently very robust parts of the lithosphere formed? A number of models have been proposed over the years, including formation by mantle plumes and shortening and thickening of existing lithosphere. This presentation will combine geophysical, geological and geochemical observations with geodynamical modelling results to try and answer this question.
