摘要：
Geophysical data collected over Goban Spur continental margin, south-west of Ireland, help to constrain mechanisms of lithospheric extension: the WAM deep seismic reflection profile obtained across the margin, as well as seismic refraction and heat-flow data favour a model of formation by pure shear. Gravity modelling along the WAM profile and subsidence curves confirm this hypothesis. However, within the context of conjugate margins, these results can be explained by two different possible models of formation.
