Movie showing the evolution of oblique rifting
in centrifuge analogue models (from Corti, 2008, Nature Geosc). Obliquity
in this model is 30° (angle between the normal to the rift
axis and the direction of extension). Note the two-phase rift evolution
with a first phase of boundary fault activity and basin subsidence,
followed by activation of en-echelon arranged internal faults obliquely
cutting the rift floor.
