Mechanisms of late-stage rift deformation: evidence from new 3D seismic data over the West Iberia margin
I describe a new 3D seismic dataset over the West Iberia margin that demonstrates the complex 3D architecture of hyperextended continental crust and exhumed continental mantle at the distal edge of the margin. Faulted continental crustal blocks show higher degrees of extension in the north than the …
