The Tibetan Plateau is the highest and widest orogenic plateau on Earth, towering over the world at an average altitude of 4,500 m and over 800 km. While far from being an exhaustive review of the existing data and models, this chapter presents some recent constraints and models that provide an integrated and improved understanding of the enigmatic plateau building. It also presents some analogue and numerical models at the lithospheric/upper mantle scale to better understand the dynamics of subduction, mantle flow and the formation of the plateau as a result. In Tibet, the global positioning system velocity field relative to Eurasia shows a dominant north-eastward motion of the plateau. At depth, seismic profiles are used to constrain the deformation of the lower crust and of the lithospheric mantle beneath Tibet.

Abstract
The Tibetan Plateau is the highest and widest orogenic plateau on Earth, towering over the world at an average altitude of 4,500 m and over 800 km. While far from being an exhaustive review of the existing data and models, this chapter presents some recent constraints and models that provide an integrated and improved understanding of the enigmatic plateau building. It also presents some analogue and numerical models at the lithospheric/upper mantle scale to better understand the dynamics of subduction, mantle flow and the formation of the plateau as a result. In Tibet, the global positioning system velocity field relative to Eurasia shows a dominant north-eastward motion of the plateau. At depth, seismic profiles are used to constrain the deformation of the lower crust and of the lithospheric mantle beneath Tibet.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
