WebRifting does not occur in continents with older and more stable interiors, known as cratons. When continental rifting does occur, the break-up pattern resembles the seams of a soccer ball, also called a truncated icosahedron. ... Cox, A., Doell, R. R. & Dalrymple, G. B. Reversals of the Earth’s Magnetic Field. Science 144, 1537–1543 (1964). WebThe rift system formed in the presence of the Afar mantle plume and far-field tectonic stresses related to subduction of the Neotethys Ocean beneath Eurasia far to the north ( Bosworth et al., 2005; Almalki et al., 2015 ), eventually leading to formation of new oceanic crust as early as 13 Ma ( Mohriak, 2024; Augustin et al., 2024 ). The formation of rift basins and strain localization reflects rift maturity. 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… reheat garlic naan
