Short summary
Continental crust comprises bodies of varying strength, formed through numerous tectonic events. When subject to extension, these areas produce distinct rift and fault systems. We use 3D models to examine how rifts form above strong and weak areas of crust. We find that faults become more developed in weak areas. Faults are initially stopped at the boundaries with stronger areas before eventually breaking through. We relate our model observations to rift systems globally.
