Laurent Jolivet est Professeur à l'Université d'Orléans au 1er Septembre 2009 International audience The respective tectonic effects of back arc spreading and continental collision in Asia are considered either as two independent processes or as closely interrelated. Extrusion tectonics assumes that the opening of the South China Sea and the left-lateral motion along the Red River fault are geometrically linked in a pull-apart manner.
