Caracterización morfoestructural del monoclinal del borde oriental del sector la Merced parroquia Malacatos

Abstract

Abstract: The work carried out on the eastern edge of the La Merced sector, Malacatos parish, was based on characterizing its structural geometry through the analysis of topographic maps, satellite images, and field surveying by means of transects at a scale of 1:10,000. In the satellite images, landform shapes were analyzed. A geometry in the shape of an open C toward the E was identified, this being the surface expression of a fold at depth. This was corroborated by the interpretation of contour lines that show patterns with the same geometry but are cut by a drainage approximately in the center of the polygon. In the transect-based survey, three lithostratigraphic sequences were identified, which were correlated with the stratigraphy of previous studies to determine their relative age. In addition, structural data from the S0 planes were measured and analyzed through stereographic projection on the Schmidt net. This allowed the definition of an asymmetric anticline with an inclined axis and axial plane and a tight interlimb angle. On the other hand, the surface expression of this anticline is a structural morphology that results from its combination with differential erosion.
