Short summary

When a continent is pulled apart, it breaks and forms a series of depressions called rift basins. These basins lie above weakened crust that is then subject to intense deformation during subsequent tectonic compression. Our analogue experiments show that when a system of basins is squeezed in a direction perpendicular to the main trend of the basins, some basins rise up to form mountains while others do not.
