Modelling the lithospheric rheology control on Cretaceous rifting in West Antarctica.
Small-scale analogue models were used to investigate the process of Cretaceous orthogonal extension in the West Antarctic Rift System. The models considered the transition from the East Antarctic Craton to a weaker lithosphere, and the results support previous hypotheses about the strong control exe...
