The Jurassic sedimentary and volcanic sequence (Cañadón Asfalto Formation) of the northwestern Chubut province was started by an extensional regime. The precise location and geometry of a segment of the Jurassic rift, located in the Cerro Cóndor area, is distinguished as a narrow, north-south trending magnetic high rendered by the sedimentary sequence, which, in turn, are displaced by east-west wrench faults evidenced by cross magnetic lineaments
