Resumen:
Within an area of around 119 km2 at Danco Coast (64° 09´ S and 60° 57´ W, (Figure 1) a geophysical onshore/offshore survey was carried out during the 2005-06, 2006-07 and 2008-09 Antarctic summers. The Upper Cretaceous to Tertiary volcanic rocks intruded by a granodioritic pluton which outcrop in coastal areas belongs to the Mesozoic magmatic arc. Leucocratic and melanocratic andesitic dykes hosted in granodiorite at Cierva Cove bear sulphide mineralization. The main structures consist of two fault systems of WNW-ESE and NE-SW orientation which delineate the morphology of onland areas and the shoreline.
