• Resumen

  • The Eastern Cordillera and Subandean Ranges betwen 23º and 24º S exhibits an E-verging basement-involved reverse faults and thrusts. Most of the faults are generated by the inversion of the N-S trending extensional faults during compressional tectonics process.

    Structural and kinematic analysis allow us to distinguish severas stages during the compressional event. The thrust faulting started at 17 to 14 Ma in westernmost tectonics units of the Eastem Cordillera and at 11 Ma in eastern thrust sheets. The compressional deformation has been transferred to the Subandean Ranges at 8,5 Ma and lasted and ¡t probably contemporaneous with the second generation of thrust (out of sequence thrust) in the Eastern Cordillera.
