• Multichannel seismic profiles in the central Bransfield Strait show structural variation mainly controlled by transform faults across the strait. Near King George Island, large displacement of the spreading axis, discontinuity and different style of the faults, intense deformation of the basement, and abrupt change in the morphology of the basin are indicative of the presence of a large fault zone. On the basis of the fault map, the central Bransfield Strait can be divided into three segments. Transform faults, including the large fault zone, form the boundaries of segments. The basinward-dipping reflectors concentrated in the central segment suggest that initial rifting activity was relatively strong in this region.
