Abstract
New and existing seismic reflection data in southern McMurdo Sound have been used to investigate
Neogene tectonic history of the Terror Rift adjacent to the Transantarctic Mountains and along the western margin of the West Antarctic Rift System. Seismic data image a young rifting episode that is largely unsampled by CRP and CIROS drill holes. Data reveal up to 3.5 km of post middle Miocene strata deposited in this part of the NNW-
SSE trending Terror Rift basin. Mapped fault trends in the southern Terror Rift parallel the axis of the basin and are
prominent in a 40 km wide zone north of Ross Island. Displacement on individual faults in this zone can exceed 100
m and faults collectively accommodate approximately 10-15 km of middle Miocene to recent extension.
