文摘

We review 3 magma-poor margins combining observations and numerical modelling. We describe three characteristic phases: (1) simultaneous faulting, (2) rift migration, and (3) break-up. Weak rheologies prolong the phase of simultaneous faulting. The rift migration phase is enabled by initial fault asymmetry and weak crust.
