Interpretation of seismic refraction measurements and gravity profiles from the Rockall Plateau area of the North-east Atlantic proves that the Plateau is a microcontinent. The depth to the Moho beneath the Plateau varies between 22 and 31 km. P wave velocities of about 6·4 and 7·1 km s−1 were obtained for the main crustal layers; these velocities may be typical of microcontinents. The Plateau is approximately in isostatic equilibrium, as too is Rockall Trough. The Trough is underlain by a thin crust, possibly of oceanic origin.
