Resumen:
|
Several active tectonic evidences are observed along Costa Recta, located eastward of Deception Island (western Antarctica): marine terraces and fluvial streams cutting a relict glacier. The height of both landforms decrease southward from Macaroni Point, appointing to a tilt movement across a fault plane. Fault planes were measured at Macaroni Point and Baily Head, with a main NNWSSE orientation, similar to the Costa Recta strike. From several scales o f measure, the orientation of the beach was established in two principal segments: N168QE, and N173QE. On the other hand, the beach and glacier dynamics and sedimentary deposits were studied. According to the morpho-tectonic analysis, we conclude that the Costa Recta beach is a retreat scarp of a submarine fault oriented NNW-SSE and located in the Bransfield Strait, although a geophysical study o f the marine bottom is needed to map the fault trace in an accurate way.
