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 ...
Late stages of breakup of the Galicia rifted margin
The Galicia margin offshore of Spain represents a magma poor end member of a rifted margin. The margin exhibits varied fault structures and complex seismic stratigraphy. The R/V Marcus G. Langseth acquired three dimensional ...
3D seismic characterization of the Peridotite Ridge in the Deep Galicia Margin
In the Galicia magma-poor rifted margin, hyperextended continental crust is separated from oceanic crust by a wide transitional zone of exhumed mantle, which contains a series of margin-parallel basement ridges. The most ...
