Estudio microtectónico en las rocas observadas en la vía San Pedro-Zambi, con la finalidad de relacionar con los procesos de deformación andina

Abstract

Abstract: This research project focused on the interpretation of microtectonic and mesotectonic structures observed in field samples and thin rock sections located along the San Pedro-Zambi Highway. These structures exhibit tectonic and microtectonic deformations resulting from the uplift of the Andes and accretionary processes over millions of years. At the mesotectonic scale, field observations revealed folds, deformations, and faults, while microtectonics allowed for the study of mineralogy, structural trends, and jagged edges based on the interpretation of the thin sections. Micro- and mesotectonic analyses allowed for the definition of foliations and structures found throughout the study area. Deformation surfaces were identified, such as the schistose foliation (S1) and the crenulation cleavage (S2), which allowed for a better understanding of the local tectonics and its relationship to the Andean Orogeny, providing greater information on the deformation processes and geological evolution of the area, which have taken place from the Paleozoic to the present.
