Evolution of Rift Architecture and Fault Linkage During Continental Rifting: Investigating the Effects of Tectonics and Surface Processes Using Lithosphere‐Scale 3D Coupled Numerical Models

Abstract Continental rifts grow by propagation, overlap and linkage of individual fault segments. These processes are influenced erosion sedimentation generate complex three‐dimensional fault‐interaction patterns. We use a 3D thermo‐mechanical model lithosphere deformation coupled with surface to investigate the coupling between tectonics, interaction rift linkage, evaluate respective characteristics crustal strength, inherited structures erosional efficiency. find that (a) weaker crust limits interactions segments, (b) major control for except if they too far apart prevent interaction, (c) efficient prolong activity, increase accommodated offset in doing so, limit segment propagation interactions. From these feedbacks, we identify five types characteristic architectures: strong intermediate efficiency, segments link form horst propagating rifts. Decreasing notch leads segmentation central horst. In case reduced strength no occurs continuous is promoted. (d) If apart, irrespective basins do not wide plateau‐like forms (e) erosion, achieved formation strike‐slip faults connecting Several simulated architectures can be identified western branch East African Rift.
