At the onset of rifting, the upper part of the lithosphere starts to extend on a series of initially unconnected normal faults, leading to the development of isolated basins. In subaerial rifts, for example, drainage at the onset of rifting is generally internal, with no element of through drainage. As the rift evolves, some of the individual fault segments grow, eventually becoming linked toget…

WebApr 1, 2024 · Active rifting is caused by the impingement of a thermal anomaly (mantle plume), producing doming, volcanism and extension (see Sengör and Burke, 1978 ). Passive rifting is related to lithospheric far-field forces pulling the lithosphere apart, notably related to subduction zones acting as boundary conditions.
