Zonas transversales en el dominio axial de la Cordillera Oriental - Bloque yacente de la Falla de Soapaga (Sátiva Sur - Sátiva Norte, Boyacá)

Abstract

Three structural domains were interpreted along the Soapaga Fault according to the observed changes of the footwall block, this after the geological mapping of a sector near the Floresta Massif in the Eastern Cordillera axial zone. The northern domain shows a regional anticlinal, which is cut by reverse mid-angle sub-parallel and fold accommodation faults. Is evident that in the in the central and southern domains a tilted syncline shares a limb with the East verging adjacent anticline. These two domains are separated by a NWW transverse zone. The Soapaga fault system is defined in the area as a trailing imbricate fan. Transverse faults may suggest the presence of a transfer zone associated to pre-existing basement anisotropies that have been reactivated during the Eastern Cordillera Cenozoic uplift.
