Structural characterization of the Magallanes-Fagnano transform fault, Tierra del Fuego, South America

Structural analyses in the area of Fagnano and Deseado lakes show different deformational events that took place in the southernmost South America. The compressional structures represent at least two deformational episodes associated with the Upper Cretaceous Andean Orogeny. A series of NE-vergent t...
