Abstract

Abstract: This work was carried out with the purpose of collecting geological information from outcrops that are difficult to access and constructing stratigraphic columns through the use of an unmanned aerial vehicle (UAV) in order to contribute information to the study of sedimentary basins. This by means of a flight plan executed in the field with a UAV, the point cloud and aerial photographs were obtained, which helped to obtain the DEM and orthophoto of the study area, serving for the geomorphological and geological interpretation, by means of 3D models, stratigraphic columns and profiles, two types of conglomerates were determined in which they were differentiated by their resistance and geological characteristics, being much more resistant the conglomerates found in the tops of the slopes (Linderos Conglomerate). Finally, the change in the geometric orientation of the strata was verified in order to contribute to the knowledge of the evolution of the basin. By means of geological profiles, we determined that the layers changed their direction being subhorizontal to the north and more inclined to the south, due to the fact that they suffered extension and sedimentation processes simultaneously, generating faulting in these when they suffered a compression process. Being observed more inclined towards the south of the study polygon, relating this process with a half-graben.
