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.

Movie showing the evolution of orthogonal rifting in centrifuge analogue models (from Corti et al., 2010, Tectonophysics). 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.

Figure showing the evolution (in cross-section) of analogue models of orthogonal rifting (from Corti et al., 2010, Tectonophysics). 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.

Movie showing a normal-gravity analogue model of oblique rifting. Obliquity in this model is 30° (angle between the normal to the rift axis and the direction of extension); the top half of the model is moving, the bottom half is stationary.

Movie showing the preparation and deformation of a strike-slip model. During deformation, the bottom half of the model is moving to the left with respect to the top half, which is stationary. During deformation, a pull-apart basin develops in the central part of the model.
