Modelling the lithospheric rheology control on the Cretaceous rifting in West Antarctica
Abstract 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 co...
