Resumen
Guamuéz-Sibundoy Monogenetic Volcanic Field (GSMVF) is located in the Northern Andes, southern Colombia, in a geomorphological depression known as the Sibundoy Valley. This area is influenced by a set of faults related to the Algeciras Fault System. To understand the tectonic activity recorded in the morpho-structural features and the interaction with the GSMVF, a morphostructural characterization via geographic information systems (GIS) was carried out. Using a digital elevation model, slopes, drainage, aspects, and lineaments on shaded relief were analyzed. Deflections in rivers and rectilinear segments were identified. The analysis shows that the lineaments concentration present in the area can be related to the damage zone of regional faults. These faults can be related to predominant continuous lineaments in the WNW-ESE, NW-SE, NNE-SSW y NE-SW directions. The lineaments in the WNW- ESE y NW-SE direction are related to the Sibundoy fault and Algeciras Fault System, while the linea- ments in the NNE-SSW and NE-SW directions are associated with the San Francisco-Yunguillo fault. In conclusion, this work reveals regional faults that have not been previously identified, and uses these faults to propose a structural model of interaction with transverse faults.
