Magallanes-Fagnano Fault
The Magallanes–Fagnano Fault is a continental transform fault. The fault marks a transform boundary between the Scotia Plate and the South American Plate, cutting across continental crust. It runs under the Strait of Magellan's western arm, Almirantazgo Sound and Fagnano Lake.
It has been suggested that the Magallanes-Fagnano Fault is a reactivated suture of pre-Jurassic age separating the basement of two terranes.
