A Tertiary igneous centre north of the Shetland Islands

Abstract
Synopsis: Marine gravity and magnetic data show the existence of a dense cylindrical body of approximately 14 km diameter centred at about 61°50′N, 00°30′W, north of the Shetland Islands. The density and remanent magnetization values derived for this body show it to be similar to the Tertiary basic intrusive bodies along the west coast of Scotland.
