BUSCADOR RECOLECTA

ANT-92 Cruise (29HE19920211) carried out on the Research Vessel Hespérides in 1992, Geology and geophysics of the Shetland Islands: Study of a triple junction zone

HESANT Cruise (29HE19921214) carried out on the Research Vessel Hespérides in 1992, Tectonics and sedimentation in the South Shetland arc and Sheckleton fracture zone (HESANT). The objectives include geodynamic aspects linked to the tectonic evolution of plates in the continental margin of the Antarctic Peninsula, paleoceanographic studies related to global changes registered by the deposits and mechanisms of continental margin construction. Among the tectonic aspects, from the establishment of the structure, the detailed reconstruction of the plate kinematics is considered, while the paleoceanographic and paleoclimatic evolution has been approached from the identification of the diposicional processes and the analysis of the seismic stratigraphy. sequential, all in order to establish the factors that have influenced the development models of the basins and continental margins linked to the Antarctic Peninsula
