3D numerical modelling of extensional systems: offset=4h
(a, b, c) Top view of elevation at t = 3Ma, 4.4 Ma and 5.8 Ma. (a) At t = 3 Ma, deformation localises in
the weak seed regions (b) At 4.4 Ma, the grabens have started
propagating towards each other and deformation localises in the
central region. (c) At t = 5.8 Ma, an oblique secondary graben is
formed in the central region. Topographic highs link different
rift segments. (d) Strain rate at t = 5.8 Ma showing formation of
complex structure. (e) 3D representation of elevation (km) at 5.8Ma.
