Mountain Belts: giants with hot-soft but vibrant hearts Other events...
A public lecture by Professor Olivier Vanderhaeghe, Université Paul Sabatier, Toulouse 3 and Adjunct Director of the Géosciences Environnement Toulouse (GET) laboratory and 2018 UWA Robert and Maude Gledden Senior Visiting Fellow.

Mountain belts have always intrigued human beings and were first looked with defiance as the home of the gods. They appeared as gigantic and resisting the assaults of the natural elements even though it was already understood in Ancient Greece that erosion could potentially play a major role in their destruction. More recently, it was realized that mountain belts are not so resistant and that they instead hide a hot and tender heart at the source of their decline. Indeed, the exhumed roots of orogenic belts is made of migmatites and granites, former partially molten rocks and magmas, respectively, that display a geological record attesting for an intimate link between partial melting, orogenic evolution and crustal differentiation from the rise of mountain belts to their collapse.

This lecture will present the evolution of ideas regarding the orogenic cycle and discuss the significance of examples taken through the Alpine belt s.l. from the Western Alps to the Aegean domain, through the Tibetan plateau. It will also propose some perspectives for future research on the deep roots of mountain belts.

Olivier Vanderhaeghe is a field geologist with additional expertise in structural geology, petrology, geochemistry, geochronology, tectonics, and geodynamics.
