SEMINARIS DE LA FACULTAT DE GEOLOGIA I L'INSTITUT DE CIÈNCIES DE LA TERRA 'JAUME ALMERA'
The 12th May 2008 Sichuan earthquake was one of the worst natural disasters in China and occurred in the Longmen Shan range, at the eastern border of the Tibetan Plateau. This belt is an unusual intracontinental mountain range because it is characterised by one of the steepest topographic gradient of the world associated with a very low convergence rate recorded by GPS across the belt (3±3 mm/yr). At longer time scale, this range was mostly formed during the Indosinian orogeny (Late Triassic), mostly characterised by a prism tectonics and affected by a more recent Miocene thick-skin tectonics.

An integrated study using both geophysics and geology was performed to understand formation and evolution processes of this range deeply related to the Tibetan Plateau history. This study highlighted the importance of the structural and thermal inheritance in the Longmen Shan, which is a key area to understand reactivation processes in intracontinental mountain belts.
