Resumen
New geophysical data (bathymetry, electrical resistivity tomography and seismic profiles) show the structural and morphological characteristic of the Peninsula Ushuaia structural high. The bathymetry and seismic data show that the structural high is bordered by two troughs controlled by the E-W Beagle channel strike-slip fault system and a NW-SE extensional system. Electrical resistivity tomography profiles allow us to identify similar oriented meso-scale structures onshore at the Peninsula Ushuaia. The collected evidence supports the idea that the NW-SE extensional system should be younger than the E-W system.
