Furthermore, multiphase rifts Received in revised form will display a greater frequency and range of styles of fault interactions than single-phase rifts. Although 28 July 2015 these physical models have yielded useful information on the evolution of fault networks in map view, Accepted 30 August 2015 the true 3D geometry of the faults and associated interactions are poorly understood. Here, we use an Available online 4 September 2015 integrated 3D seismic reflection and borehole dataset to examine a range of fault interactions that occur
