Bacia Dove [Mar de Scotia – Antártica]. Processamento e Interpretação de Novos Dados de Sísmica 2D.

The structure of the transcurrent limit between the Scotia and Antarctica plates, and the development of small oceanic basins along the South Scotia Ridge is poorly known. New 2D reflection seismic data from the Dove Basin in the southeastern portion of the Scotia Sea, acquired during SCAN 2004 cruise, has being processed and interpreted. A preliminary interpretation suggests that the tectonic development of the Dove basin agrees with the others small oceanic basin near round and show particular asymmetric development of the spreading axis, indicating a complex setting of stress, displacement and rotation of the continental blocks.
