Contrasted models of rifts basins |

 |
A/ Domino fault block model in which both the faults and the intervening fault blocks rotate during extension.
B1/ Planar kink fault geometry
B2/ Listric fault-subhorizontal décollement.
In both B1 and B2 horizontal displacement (h) on the décollement fault creates a potential void bewteen the hanging wall and footwall which is erased by the collapse of the hanging wall along antithetic faults dipping at 45º in B1, and vertical faults in B2. |
