Summary Gravity, magnetic and bathymetric data from Rosemary Bank and the northern end of Rockall Trough are used to produce a geological model for the Bank and the crust beneath. The interpretation, made in three dimensions, shows that Rosemary Bank is an extinct volcano underlain by a large magma chamber. The volcano may be Mesozoic in age. Anton Dohrn Kuppe is probably an identical feature.
