Abstract
Marine geophysical studies of the northwestern Weddell Sea show several interesting stratigraphic and tectonic features. Synthesis of the ODP drilling results on the South Orkney Microcontinent with the Circum-Antarctic depositional model allows identification of the main reflectors within the Cretaceous-Cenozoic sedimentary cover. The age and composition of pre-rift, syn-rift and post-rift units probably vary throughout the region. The observed seismic pattern of the Jane Bank suggests a young asymmetric zone of extension. A seismic record across the South Orkney Trough and Central Scotia Basin indicates an association with an accretion zone and spreading centre.
