Abstract
Identification of strike-slip faulting indicators, along the trace of the Soapaga and Boyacá faults from Landsat TM5 images, suggest a transpressive tectonic regime in the axial zone of the Eastern Cordillera of Colombia. The array of the Soapaga and Chaguacá faults conforms a duplex structure, which together with the Boyacá Fault indicate that the lateral left displacement, typical of the Bucaramanga Fault, continues up to an approximate latitude of 5º50’. Southwards of this latitude, some regional features indicate right-lateral displacements along the Soapaga and Boyacá faults and along the thrusts related to the Boyacá Fault. The continuity of the major NE longitudinal faults towards the Sabana de Bogota is suggested, as well as the existence of basement faults related to transverse lineaments, which extensional or transtensional movements can influence the seeping of hydrothermal fluids.
