Abstract
A seismic and magnetic profile recorded in the Western Ross Sea, near Coulman Island, is analyzed. The seismic line is characterized by some buried structures whose origin is not fully understood. Automatic bidimensional velocity analysis and tomographic inversion, as well as inversion of the magnetic data over the examined profile were performed. It was concluded that the observed structures are due to magmatic intrusions (sill and dikes) which caused the deformation of the upper sedimentary sequences and the consequent anticlinal structure, successively remodelled by the erosional action of the Antarctic glaciers. -from Authors
